Thomas & Betts LTXES11B-A LFMC XTMP 4IN BLK 8M/25FT

Metal core. The LTXES11B-A is built on galvanised steel with a black jacket over it, which is what makes it liquid tight flexible metallic conduit rather than the nonmetallic (LFNC) type. If your drawing calls for LFNC or a plastic raceway, this is the wrong product.

No. The LTXES11B-A ships as conduit only, a 25 ft (8 m) coil. You order liquidtight connectors separately, sized to match the conduit trade size and the box or enclosure knockout, and you need one at each termination.

One coil of the LTXES11B-A runs 25 ft (8 m). That is the full put-up, so a run longer than 25 feet means ordering more than one coil or planning a coupling point in an accessible location.

Flexible liquidtight is used where the raceway has to absorb vibration or movement and still keep water out, which is why it shows up on motor whips, HVAC condensing units, pumps and equipment on rooftops. Rigid and EMT are the better choice for long fixed runs and where physical protection matters more than flexibility. The LTXES11B-A is the flexible metallic version, galvanised steel core in a black jacket.

Don't count on it. The LTXES11B-A has a galvanised steel core, but standard practice on liquidtight flexible metallic runs is to pull a separate equipment grounding conductor sized to the circuit rather than rely on the flex and its fittings, particularly on longer runs and larger breakers. Size the ground conductor per the overcurrent device and include it in your conductor fill.

Order it as Thomas & Betts LTXES11B-A. That single part number covers the black galvanised steel liquid tight flexible metallic conduit in the 25 ft (8 m) coil; there is one configuration, so there is no finish or length option to specify on the order.
