Thomas & Betts LTBUS06R-B LFMC SPLP UL 1-1/2IN RED 15M/50FT

The LTBUS06R-B is 1-1/2 inch trade size liquid tight flexible metallic conduit supplied as a 50 foot (15 m) coil. One coil is one orderable unit, so figure your runs against 50 feet before deciding how many you need.

It is metallic. The LTBUS06R-B has a galvanized steel core with a liquid tight outer jacket, which is what separates LFMC from non-metallic liquid tight (LFNC). The steel core gives the run crush and pull resistance that a plain plastic hose does not, and it is the reason this type is used for motor whips, pump connections, and equipment terminations where the conduit has to flex but still take abuse.

No. The LTBUS06R-B ships as conduit only, a 50 foot (15 m) coil. You need to order liquid tight connectors separately, sized 1-1/2 inch to match, and you need two per run (one at each termination) plus sealing rings or locknuts depending on the enclosure. Budget the fittings into the order before it leaves.

The red jacket on the LTBUS06R-B is a color-coded identifier. On a job where circuits or systems have to be told apart at a glance, running the red jacket for one system and a different color for another keeps the identification visual instead of relying on tags. Electrically and mechanically it is the same 1-1/2 inch liquid tight metallic conduit with a galvanized steel core.

That is the usual application for it. Liquid tight flexible metallic conduit is used for the final flexible connection to equipment that vibrates or moves, and for wet or outdoor locations where a rigid raceway cannot absorb that movement. At 1-1/2 inch it is a larger trade size, so it suits feeders to bigger motors, rooftop units, and pump skids rather than small control whips. For a light fixture drop or a small control circuit, step down to a smaller trade size instead of pulling 1-1/2.
