Thomas & Betts LTGUS01B-C LFMC GP UL 3/8IN BLK 30M/100FT

The LTGUS01B-C is 3/8 inch trade size liquid tight flexible metallic conduit, supplied as a 100 foot (30 m) coil. That 3/8 inch size is the small trade size used for short whips and tight equipment drops, so if you're running multiple conductors for a larger feeder you'll want to step up a trade size.

It's metallic. The LTGUS01B-C uses a galvanised steel core strip with a black jacket over it, which is what separates LFMC from the all-plastic LFNC type. The steel core is what gives it crush resistance and the mechanical body that liquid tight steel fittings bite onto.

That's the typical use for it. Liquid tight flexible metallic conduit handles the vibration and movement at motors, compressors and rooftop units while the jacket keeps water out of the raceway. The 100 foot coil gives you enough for a run of short whips across a site rather than a single fixed length.

Go metallic, like the LTGUS01B-C, where you need the mechanical strength and crush resistance of a galvanised steel core, and where the installation benefits from a metal raceway path at the fittings. Non-metallic liquid tight is lighter and easier to pull through tight bends, but it gives you no metal core, so it's the weaker choice anywhere the conduit can be stepped on, kicked or hit by equipment.

Order it as Thomas & Betts LTGUS01B-C. It's a single configuration: 3/8 inch, black, 100 foot coil. There are no finish or length choices to specify, so the only decision left is how many coils you need and which liquid tight fittings go with them.
