Thomas & Betts LTGES01B-L LFMC GP 3/8IN BLK 300M/1000FT

One roll of the LTGES01B-L is a 1,000 ft (300 m) coil of 3/8 inch liquid tight flexible metallic conduit. That is a bulk reel quantity, so it suits shops pulling repeated short whips for motor, HVAC, or rooftop equipment connections rather than a one-off run.

You need 3/8 inch trade size liquidtight connectors, since the LTGES01B-L is 3/8 inch LFMC. Fittings are a separate order, and a liquidtight run only stays liquidtight if the connectors are rated for it, with the sealing gland and gasket, not plain flex connectors.

The core is galvanised steel, jacketed in a black outer covering. Steel core LFMC gives you a flexible raceway that still takes mechanical abuse, which is why it is the usual choice for equipment whips, pump and compressor connections, and anywhere vibration would fatigue rigid conduit.

Order it as Thomas & Betts LTGES01B-L. That number covers the 3/8 inch black galvanised steel LFMC in the 1,000 ft coil, so distributors quoting against a spec should match the full suffix rather than a shortened LTGES01B.

Metal core liquidtight like the LTGES01B-L is what you reach for when the run can take physical abuse or needs the mechanical strength of a galvanised steel helix. Nonmetallic liquidtight is lighter and easier to handle but gives up that steel armor. At 3/8 inch, this size is aimed at short whips and small control runs, not multi-conductor feeders.

Same 3/8 inch galvanised steel liquid tight flexible metallic conduit, just a black jacket instead of gray. Color is the difference buyers use to separate circuits or match existing installs on a site, so if the other whips on the building are black, this matches them.
