Thomas & Betts LTZES11B-A LFMC HLFR 4IN BLK 8M/25FT

You need liquidtight connectors matched to the conduit's trade size, not standard flexible metal conduit fittings. LFMC fittings seal against the jacket with a gland or ferrule to keep the liquidtight rating intact at the box; a plain FMC squeeze connector will not seal. Order the connectors separately, they do not come on the roll.

Each roll of the LTZES11B-A is 25 ft (8 m) of liquid tight flexible metallic conduit. If you are running multiple whips or feeding several rooftop units, count your total footage plus slack at each termination before deciding how many rolls to pull.

Galvanized steel core with a black outer jacket. The steel core is what gives liquid tight flexible metallic conduit its crush resistance and its ability to serve as a metallic raceway, while the jacket keeps moisture out. If a job spec calls specifically for an aluminum-core LFMC, this is not that product.

Plan on pulling an equipment grounding conductor. LFMC has a galvanized steel core that is metallic, but flexible metallic raceway is only permitted as the sole ground path within limited size and length conditions, so most electricians and inspectors expect a separate green wire in the whip. It costs little and removes the argument at inspection.

Black is the standard jacket color for LFMC used in wet and outdoor locations, and the LTZES11B-A is supplied in black. It is the usual choice for rooftop HVAC whips, pump and motor connections, and equipment where the run is exposed to weather and vibration.

Order it by Thomas & Betts part number LTZES11B-A. That number covers the black 25 ft (8 m) roll of liquid tight flexible metallic conduit with the galvanized steel core.
