Thomas & Betts LTMES01G-C LFMC EMCMIDHF 3/8IN GRY 30M/100FT

It's 3/8 inch trade size, supplied as a 100 foot (30 m) coil. That's the size most commonly run for motor whips, small control drops, and short flexible connections to equipment where a larger raceway would be overkill.

Liquid tight flexible metallic conduit like the LTMES01G-C has a metal core under the jacket, so it gives mechanical protection and the physical ruggedness you want on motor connections, rooftop units, and equipment that vibrates. Non-metallic liquidtight is lighter and cheaper but offers no metal armor, so it's used where crush and abrasion aren't a concern. For a flexible final connection at a compressor, pump, or fan motor, the metallic type is the usual call.

The manufacturer part number is LTMES01G-C from Thomas & Betts, a 3/8 inch grey liquid tight flexible metallic conduit in a 100 foot (30 m) coil. Quote that number and you'll get the same item, same size, same jacket color.

Grey. On installs where color is used to separate systems (power versus control versus instrumentation), grey is the common general-purpose jacket color, so it usually matches what's already run in a plant or mechanical room. If your spec calls out a specific jacket color for a circuit class, confirm grey is the one assigned to it.

Bronze core, jacketed in grey. It's the metal core that gives this conduit its crush and abrasion resistance compared with a non-metallic liquidtight of the same size.
