Picking the right conduit body or raceway matters more than most people think. Run a new workshop circuit, repair a damaged exterior run, or extend a pool pump feed, and the wrong fitting means callbacks. I’ve spent enough time around electrical projects to know that aluminum and PVC options each solve different problems, and that thread size, hub style, and cover type quietly decide whether the install goes smoothly.
I pulled together eight solid options covering rigid LB bodies, flexible steel raceway, and liquid-tight PVC kits. Each one fits a specific job, so skim for the scenario that matches your project before locking in a choice.

The Picks, Examined More Closely
An LB conduit body creates a 90-degree turn in a rigid run and gives you a hand hole for pulling wire or making splices down the road. The Morris 14054 in copper-free die-cast aluminum handles that role for 1-1/2 inch threaded rigid or IMC (intermediate metal conduit) at outdoor service entrances, garage feeders, and similar wet or exposed spots.
The flat back makes it sit tight against a wall or eave, and the gasketed cover keeps the rain out when properly seated. For most homeowners adding a single 240-volt circuit or finishing a detached workshop feed, this is the kind of fitting that does the job without overspending.
What Helps Most
- Tapered NPT (National Pipe Thread) hubs form a tight seal with standard rigid pipe, reducing the chance of a wobbly joint.
- Gasketed stamped cover sheds rain and dust, so you can mount it on an exterior wall with confidence.
- Die-cast aluminum body resists rust far better than cast iron in coastal or damp climates.
- Hand hole opening gives you room to pull conductors or add a splice without disassembling the run.
Points To Keep In Mind
- At 1-1/2 inch, the body is sized for specific conductor counts, so verify your wire fill against the NEC chart for your gauge.
- Aluminum threads can gall if cross-threaded; a light touch and proper thread sealant make installation smoother.

A Better Fit Elsewhere
Anyone wiring a smaller branch circuit should reach for the Ohhose 25 Ft Liquid-Tight Conduit Kit instead, since 1/2 inch non-metallic flex suits those runs far better.
Flexible Metal Conduit (FMC), sometimes called Greenfield, is the spiraled steel raceway that bends around obstacles without elbow fittings. The Wesiti 1.25 inch x 100 ft roll covers long interior runs in exposed locations like a basement ceiling, garage, or barn loft where rigid pipe is overkill but plastic wouldn’t stand up to physical damage.
Compared to the Morris 14054, this is a continuous raceway rather than a single fitting, so the project scope is very different. Galvanized steel shrugs off the kind of bumps and scrapes that would crack PVC, which matters in a working shop.
Everyday Advantages
- 100 foot length means fewer couplings and joints across a long garage or outbuilding run.
- Galvanized steel construction tolerates physical abuse far better than PVC in a working space.
- Flexible spiral cuts to length with a hack saw and a few rotations of a screwdriver, no special bender required.
Trade-Offs To Consider
- Steel flex is not water-tight, so outdoor or wet-location use calls for a different product, like the Ohhose liquid-tight kits below.
- Pulling wire through 100 feet of spiral can be tiring; a fish tape and pulling lubricant are worth having on hand.
Feature Card
Who Should Grab It
Shop owners and homeowners running a long exposed interior feeder where rigid conduit would be slow to install.
Where A Sibling Pick Shines
For a 25 foot outdoor pump or AC run, the Ohhose 25 Ft Liquid-Tight Conduit Kit is a more focused, weather-ready choice.
Liquid-tight flexible non-metallic conduit (LFNC) is the go-to for short outdoor or damp runs where you need a watertight sleeve around individual conductors. The Ohhose 25 ft kit pairs the conduit itself with 4 straight and 3 90-degree fittings, so you can go from a panel, around an obstacle, and into a disconnect without buying extras.
Where the Wesiti steel flex above suits interior mechanical spaces, this 1/2 inch PVC track handles a single dedicated circuit outdoors. It is the kit I would hand to someone wiring an air conditioner disconnect on a patio wall.
Notable Upsides
- Antioxidant PVC jacket resists UV, oil, and mild chemicals, suiting outdoor and direct-burial applications.
- Smooth inner wall reduces friction, so pulling THHN (thermoplastic high-heat-resistant nylon-jacketed) wire takes less effort.
- Included straight and 90-degree connectors remove the guesswork of sizing fittings to the conduit.
Honest Caveats
- At 25 feet, this kit covers one focused project; bigger jobs may need the 50 or 100 ft versions further down the list.
- Non-metallic conduit needs proper support straps, since it sags more than steel in long horizontal runs.
Right Fit For
First-time installers and homeowners handling a single AC unit, pump, or outdoor outlet where the fittings and conduit arrive together.
Look Elsewhere When
Anyone feeding a subpanel or running a multi-circuit yard setup should jump up to the Ohhose 50 ft or 100 ft liquid-tight kits for fewer couplings and a more comfortable margin.
A C-type conduit body is a straight-through pull box with access from one side, used when you need a hand hole in the middle of a long rigid run or want to create a junction for a tap. The TayMac RLC150 in die-cast aluminum is built for 1-1/2 inch threaded rigid or IMC and ships with the matching stamped cover.
Compared to the Morris 14054, which turns the run 90 degrees, this fitting keeps the conductors going in the same direction. It is the kind of piece I would specify where a feeder crosses a wide room and needs a mid-point pulling aid.
Benefits That Matter
- Powder-coated finish holds up to shop conditions and resists corrosion over time.
- Included NBR (nitrile butadiene rubber) gasket keeps incidental splashes and dust out of the conductor cavity.
- Die-cast aluminum keeps the body light enough to mount on a strut channel without extra bracing.
Possible Compromises
- C bodies create one access point, so for 90-degree direction changes you still need an LB like the Morris 14054.
Quick Facts
Who It Suits Best
Commercial electricians and serious DIYers building a long indoor rigid feeder that needs a mid-run pull point.
Swap It Out When
Homeowners adding a small exterior receptacle are better served by the Ohhose 25 ft liquid-tight kit, which arrives as a complete package.
Step up to a 2 inch rigid run and you need a much bigger LB to handle the bend radius and the larger conductor fill. The Sealproof Weatherproof LB is cast in copper-free aluminum with a powder-coated shell, paired with a stamped steel cover and gasket for outdoor use.
The honest read is that 2 inch bodies like this are rarely a one-off DIY purchase; they tend to show up on small commercial service entrances, shop feeders, and large equipment drops. It is a heavier-duty sibling to the Morris 14054 covered above.
The Good Stuff
- 2 inch hubs accept a large feeder bundle without crowding the conductors against the body wall.
- Powder coat extends the service life in salt-air or humid climates.
- Threaded hubs and gasketed cover make a sealed assembly when used with rigid or IMC.
Worth Noting
- The size and weight call for solid mounting hardware; a single drywall anchor will not hold this body.
- Verify conductor fill with the NEC charts before pulling large gauge wire through a 2 inch LB.
Best Suited To
Electricians installing a 2 inch service entrance, large equipment feeder, or commercial lighting tap.
Reach For A Different Pick When
Smaller residential branch circuits in 1/2 inch are not the right fit here, so the Ohhose 25 ft liquid-tight kit is the more appropriate match.
The 50 foot Ohhose kit doubles the run length of the 25 ft version and adds an extra straight and 90-degree fitting. That extra headroom makes it easier to handle a multi-outlet patio, a small outbuilding feed, or two related outdoor appliances from a single kit.
Same antioxidant PVC jacket and smooth interior as the smaller kit, so the wiring experience feels familiar. The 5 straight and 4 angle connectors let you change direction several times without scrambling for additional parts.
Notable Gains
- 50 foot length handles two short outdoor runs or one longer one without an extra purchase.
- Higher fitting count gives flexibility for routing around corners, posts, or existing utilities.
- UV and corrosion resistance keeps the jacket from cracking after a couple of seasons in the sun.
Where It Is Less Suited
- Non-metallic conduit still requires more support straps than rigid pipe, and longer runs mean more straps on the shopping list.
Key Attributes
Whose Shelf It Belongs On
Homeowners running multiple outdoor outlets, a pool pump, and a patio light from a single coordinated kit.
Skip It When
Larger property runs that genuinely need 100 feet of run will be better served by the Ohhose 100 ft liquid-tight kit later in the list.
At 100 feet, this is the largest of the Ohhose liquid-tight kits and the most generous in fittings, with 6 straight and 5 angle connectors. It targets whole-yard landscape lighting, a detached garage feeder, or a long irrigation control run where one continuous 1/2 inch sleeve is preferred over multiple short segments.
Compared to the 25 ft and 50 ft kits, the difference is mostly scale rather than material. The same antioxidant PVC and smooth interior carry over, so wire pulling stays consistent across the run.
Advantages To Know
- 100 foot length covers an entire property edge or outbuilding loop in a single conduit purchase.
- Largest fitting count in the line reduces mid-project runs to the hardware store.
- Antioxidant jacket keeps the conduit serviceable after years of direct sun exposure.
Factors To Consider
- Pulling wire through 100 feet of 1/2 inch flex is a workout; a quality fish tape is a worthwhile add-on.
- Storing leftover flexible conduit neatly takes a fair amount of shop or garage space.
Made For
Property owners planning a large landscape lighting or irrigation project who want one coordinated kit on hand before they start.
Consider Something Else When
Short, single-circuit jobs are not a good use of a 100 foot roll, so the Ohhose 25 ft kit usually fits that work better.
When the project calls for a short but high-capacity feeder segment, the Wesiti 2 inch x 25 ft galvanized steel flex fills a niche that rigid conduit handles awkwardly. It works well as the final flexible leg between a panel and a rigid riser, or as a service entrance whip where some movement or vibration is expected.
You may find the 2 inch diameter overkill for branch circuits, but for subpanel feeders and equipment drops it carries a useful volume of larger gauge wire. Compared to the 1.25 inch x 100 ft Wesiti earlier, this is the shorter, heavier cousin for a different kind of job.
Strengths Worth Knowing
- 2 inch diameter accepts large feeder bundles without forcing tight bends.
- 25 foot length is a manageable amount to cut and fit in a single afternoon.
- Galvanized steel flex tolerates physical contact and vibration better than PVC alternatives.
Some Limits To Know
- Steel flex is not rated for wet locations, so it stays indoors or under cover.
- 2 inch FMC is heavier and harder to bend by hand than smaller diameters, so a helper or proper tool helps.
Perfect Match For
Electricians finishing a subpanel feeder or motor lead where a short flexible steel segment is required by code or common practice.
Not Your Match When
Long interior homerun pulls will eat through 25 feet quickly, so the Wesiti 1.25″ x 100 FT Flexible Galvanized Steel Conduit is the more practical fit.
Picking The Right Conduit For The Job
Choosing between a conduit body, a flexible steel raceway, and a liquid-tight PVC kit comes down to where the wire runs and how exposed it will be. Indoor mechanical spaces with no moisture call for FMC like the Wesiti rolls, since the galvanized steel handles incidental bumps and bending without extra elbows. Outdoor service entrances, garage exteriors, and damp locations push you toward liquid-tight PVC kits from Ohhose, where the sealed jacket protects individual conductors from water and UV. For pull points and direction changes on rigid runs, die-cast aluminum bodies like the Morris 14054, TayMac RLC150, and Sealproof 2″ LB are the structural backbone of the system.
Size matters as much as material. A 1/2 inch non-metallic kit covers most branch circuits, while 1-1/2 inch and 2 inch bodies handle subpanel and service entrance feeders. Always match the conduit body trade size (its nominal thread diameter) to the pipe and to the conductor fill allowed by the National Electrical Code for the wire gauges you intend to pull.
For homeowners and trade pros, the practical question is project scope. A single AC disconnect points to the 25 ft Ohhose kit. A whole-yard lighting plan leans toward the 100 ft version. A workshop subpanel often wants the larger Wesiti steel flex plus a Sealproof LB for the outside corner. Choosing the right piece for the right section of the run is what makes the difference between an installation that lasts decades and one that needs rework.
What Often Gets Overlooked In This Category
Where Shoppers Go Wrong
The most common slip-up is matching the wrong conduit family to the location. Picking a galvanized steel FMC roll for a pool pump feed, or an LB body without a gasket for an outdoor eave mount, both end in moisture intrusion. Conduit fill is another quiet trap; a 1/2 inch sleeve cannot safely carry the same conductor count as a 1 inch sleeve, and undersized raceways overheat under load. Check the spec sheet and the NEC tables before ordering, not after the wire is on the truck.
Where The Extra Money Goes
Stepping up to a 2 inch Sealproof LB or a longer Ohhose kit costs more up front, but the payoff shows up in fewer couplings, easier wire pulls, and a longer service life. Premium die-cast aluminum bodies with powder-coated finishes resist corrosion in coastal or industrial air far better than economy castings, which is the kind of difference you only notice years later. Paying more buys material thickness, tighter tolerances on the threads, and gaskets that actually keep water out, all of which add up across a long run. For one-off short projects, the value pick is fine, but for a permanent service entrance or a large yard, the upgrade is worth it.
Frequently Asked Questions
What is the difference between a conduit body and conduit itself?
A conduit body is a fitting that joins sections of conduit, provides a hand hole for pulling wire, or changes the direction of a run. The conduit is the tube or raceway that carries the wire between fittings.
Can I use aluminum conduit bodies outdoors?
Yes, copper-free die-cast aluminum bodies with gasketed covers are commonly used for outdoor service entrances, eave mounts, and exposed runs where corrosion resistance and weather sealing matter.
What is FMC conduit used for?
Flexible Metal Conduit, also called Greenfield, is a spiral steel raceway used indoors in exposed locations like basements, garages, and workshops where rigid pipe is overkill but the wire still needs physical protection.
Is liquid-tight non-metallic conduit safe for direct burial?
Many LFNC products are rated for direct burial and outdoor exposure, but always check the jacket markings and local code before laying it in a trench without conduit sleeves.
Do I need a separate connector for each end of flexible conduit?
Yes, straight or angle connectors are required to terminate flexible conduit at boxes, panels, and enclosures, and most kits include enough fittings to cover the run they ship with.
Wrap Up
The right aluminum electrical conduit depends on where the wire is going and what kind of environment it has to survive. Rigid aluminum bodies anchor the corners, FMC handles long interior flex runs, and liquid-tight PVC kits carry branch circuits through outdoor and damp spots. Pick the product family first, match the size to the conductor fill, and double-check the fittings before ordering. That is the path to an install you will not have to revisit.
