Thomas & Betts LTXES01B-C LFMC XTMP 3/8IN BLK 30M/100FT

It's 3/8 inch trade size liquid tight flexible metallic conduit, supplied as a 100 foot (30 m) coil. One coil covers 100 feet of run, so figure your total footage plus slack at each termination before deciding how many coils you need.

Metal core. The LTXES01B-C is built on a galvanised steel strip with a black liquidtight jacket over it, which is what separates LFMC from the nonmetallic (LFNC) versions that use a plastic core. If your drawing calls out liquidtight flexible metal conduit, this is the metallic type.

Liquidtight flexible metallic conduit is the type specified where an ordinary flex would fail, meaning damp, wet, and oil-exposed locations. The LTXES01B-C carries the jacketed liquidtight construction over a galvanised steel core, which is the whole reason to pick LFMC over standard flexible metal conduit. Your local inspector still governs the specific installation, so match it against the section of code your job is built to.

Order by Thomas & Betts MPN LTXES01B-C. That's the 3/8 inch black liquidtight flexible metallic conduit in the 100 foot (30 m) coil, so it matches existing runs of the same size and color for MRO restock or standardizing across buildings.

At 3/8 inch trade size the fill is tight, which is why it's used for equipment whips rather than multi-circuit runs. Conductor count depends on wire size and insulation type, so run the fill calculation for your actual conductors instead of assuming. If the count pushes you over, step up to a larger trade size rather than forcing it, since a 3/8 inch coil won't pull cleanly if it's overfilled.

Color is jacket color. The LTXES01B-C is black, which crews often standardize on for exterior and mechanical room work where gray stands out, or simply to keep one color across a facility. The conduit underneath is the same galvanised steel liquidtight construction either way.
