Thomas & Betts LTBUS05L-B LFMC CMP UL 1-1/4IN BLU 15M/50FT

The LTBUS05L-B is 1-1/4 inch trade size liquid tight flexible metallic conduit, supplied in a 50 foot (15 m) coil. One coil covers a single 50 foot run or several shorter whip drops, so figure your total footage before ordering multiple coils.

Blue jacket. On a job that color-codes raceways, the blue outer jacket on the LTBUS05L-B lets an electrician or facility crew identify the circuit type or system at a glance without pulling a cover. Electrically and mechanically it is the same construction as the standard product: galvanized steel core with a liquid tight outer jacket.

Galvanized steel core under the jacket. That is what gives the conduit its crush and pull resistance and makes it a metallic raceway rather than a nonmetallic one, which matters when you are deciding whether the raceway itself can serve any grounding function or whether you are running a separate bonding conductor.

That is the normal use for it. Liquid tight flexible metallic conduit like the 1-1/4 inch LTBUS05L-B is the raceway used where a rigid run has to transition to equipment that vibrates or moves, such as motors, compressors, pumps, and rooftop HVAC units, and where the connection is exposed to moisture. The flexible steel core absorbs vibration that would eventually crack a rigid conduit connection.
