Thomas & Betts LTBUS06L-D LFMC CMP UL 1-1/2IN BLU 45M/150FT

The LTBUS06L-D is 1-1/2 inch trade size liquid tight flexible metallic conduit, supplied as a 150 foot (45 m) coil. One part number gets you the full coil, so for a run you are sizing against the coil length rather than ordering by the foot.

Blue jacket is used to color-code a circuit or system so it can be identified at a glance in a plant or mechanical room where several conduit systems share the same tray or rack. Electrically and mechanically it is the same liquid tight flexible metallic conduit as any other jacket color; the blue is for identification, not a different construction.

It is built on a galvanized steel core with a jacket over it, which is what makes it liquid tight flexible metallic conduit rather than the nonmetallic type. The steel core gives the run mechanical protection and crush resistance that a plain nonmetallic liquid tight hose does not.

Go metallic when the whip is exposed to physical abuse, needs the mechanical strength of a steel core, or where you want the metal core for the raceway itself. The LTBUS06L-D is the metallic version, galvanized steel core with a liquid tight jacket. Nonmetallic liquid tight is lighter and easier to pull through tight bends, but it gives you no metal armor. For a 1-1/2 inch feed to equipment that vibrates, the metallic version is the usual choice.

Liquid tight flexible metallic conduit is the product type used where the raceway sees moisture, washdown, oil, or weather, which is the whole point of the liquid tight jacket over the steel core. The LTBUS06L-D is that type in 1-1/2 inch. For any specific installation, match it to the location class your inspector is holding you to.

Order by the manufacturer part number LTBUS06L-D. That number pins the brand, the 1-1/2 inch trade size, the blue jacket, and the 150 foot (45 m) coil in one identifier, so a second order matches the first coil already on the rack.
