Thomas & Betts LTGCS11B-A LFMC GP CSA HD 4IN BLK 8M/25FT

The LTGCS11B-A is a 4 inch trade size liquid tight flexible metallic conduit supplied as a 25 ft (8 m) coil. That is one continuous length per coil, so plan your run against the 25 ft figure before ordering quantity.

It is metallic. The core is a galvanised steel strip helically wound and jacketed, which is what makes it a liquid tight flexible metallic conduit (LFMC) rather than the plastic LFNC type. The steel core gives it the crush resistance and mechanical protection non-metallic flex does not, and it is the reason this style is used where the whip has to survive traffic or equipment vibration.

Standard FMC has no jacket and is for dry interior use only. The LTGCS11B-A is the liquid tight version, with a sealed outer jacket over a galvanised steel core, so it is the one to run to outdoor or wet location equipment, rooftop units, pumps and compressors. The tradeoff is cost and bend radius: at 4 inch trade size this is a large, stiff whip, so keep the runs short and use liquid tight connectors sized to match the conduit at both ends.

Yes. The LTGCS11B-A ships as a 25 ft coil of conduit only. You need a liquid tight connector at each termination, sized 4 inch to match, plus sealing rings or gaskets if the enclosure entry has to stay rated. Order the terminations at the same time, since a 4 inch liquid tight fitting is not something most trucks carry as stock.

This part number is the coil configuration: LTGCS11B-A, 4 inch, 25 ft (8 m) per package. If your spec calls for cut lengths from bulk reel stock, that is a different order configuration. Order by the LTGCS11B-A number when you want the packaged 25 ft coil.

Black. On exposed exterior runs black jacket is the usual specification because it holds up better to sunlight than light colored PVC, and it matches most equipment and strut work on a rooftop or mechanical yard.
