Thomas & Betts LTGES03B-K LFMC GP 3/4IN BLK 150M/500FT

It's 3/4 inch trade size liquidtight flexible metal conduit, supplied as a 500 foot (150 m) continuous run. Model number is LTGES03B-K. If you're running a handful of short motor whips, that's a lot of conduit for one job, but it's the standard reel length for a contractor stocking a truck or a maintenance shop.

Galvanized steel core with a black outer jacket. The steel strip core is what makes this a metallic conduit rather than the nonmetallic liquidtight (LFNC) type, so it gives mechanical protection and the metal path that flexible nonmetallic conduit cannot.

LFMC like the LTGES03B-K is the usual pick where the whip needs physical toughness as well as a wet-location jacket: rooftop condensing units, pumps, and motors where something may get stepped on or knocked. Nonmetallic liquidtight is lighter and easier to pull through tight bends, and it's favored where corrosion is the bigger concern than impact. Both handle vibration at the equipment; the metal core is the one that takes abuse.

The black PVC jacket is the standard general purpose LFMC color and the one normally specified for outdoor equipment connections, where black pigment is what gives the jacket its sun resistance. Gray jacketed LFMC is the same construction in a different color, typically chosen to match indoor equipment and raceway.

Yes. It's a continuous 500 foot (150 m) reel meant to be cut to length on the job. Cut the galvanized steel core square so the jacket seats properly in the liquidtight gland, and ream the cut end before pulling conductors.
