Thomas & Betts LTAES12B-A LFMC ALUM 5IN BLK 8M/25FT

Each coil of the LTAES12B-A runs 25 feet, which is 8 meters. If you are running a longer feed to a rooftop unit or a pump skid, plan on multiple coils plus the liquid tight connectors at each termination, since fittings are ordered separately from the conduit itself.

Aluminum. The LTAES12B-A is an aluminum-core liquid tight flexible metallic conduit with a black jacket. Aluminum core keeps the coil lighter and easier to handle than a steel-core LFMC of the same length, which matters on overhead runs and long pulls where an electrician is working off a lift.

Liquid tight flexible metallic conduit is the type used for exactly that: the last few feet into a motor, compressor, or pump where the equipment vibrates and the area sees water or washdown. The aluminum LTAES12B-A gives you the flex for the vibration break plus a jacketed, liquid resistant covering. If the run is dry indoor and there is no movement or moisture, standard flexible metal conduit (FMC, no jacket) is the cheaper and more common choice; if the run is fixed and exposed, rigid or EMT is the better call and you use LFMC only for the whip at the end.

It will not match visually. The LTAES12B-A jacket is black, so on a roof or mechanical room where the existing whips are gray jacketed LFMC it will read as a different product even though it does the same job. For facilities standardizing appearance across a fleet of units, pick one jacket color and stay with it; the black version is common where UV exposure and outdoor runs are the concern.

Order it as Thomas & Betts LTAES12B-A. That single part number covers the black aluminum LFMC in the 25 foot (8 meter) coil, so there is no separate length or finish option to specify on the purchase order.
