Thomas & Betts LTGES13B-A LFMC GP 6IN BLK 8M/25FT

Each coil of the Thomas & Betts LTGES13B-A runs 25 ft (8 m). If a run needs more than that, order multiple coils and join them with liquid tight connectors, which are sold separately.

The core is galvanized steel, spiral wound, with a black jacket over it. That steel-plus-jacket construction is what makes liquid tight flexible metallic conduit the usual choice for wet, damp and outdoor runs such as rooftop HVAC whips, pump and motor connections, and exterior equipment drops, where plain flexible metal conduit (FMC, or Greenfield) is not suitable.

Metallic liquid tight, like this Thomas & Betts product, has a galvanized steel spiral core under the jacket, so it gives physical crush and impact protection and the metal core can serve as part of the raceway path where the fittings are listed for it. Nonmetallic liquid tight (LFNC) is lighter and cheaper but has no steel armor, so it is better suited to protected indoor runs and short whips where abuse is not a concern. Pick the metallic version for exposed equipment connections, mechanical rooms and rooftops.

Order it as Thomas & Betts LTGES13B-A. That is the manufacturer part number for the black jacketed galvanized steel liquid tight flexible metallic conduit in the 25 ft (8 m) coil.

The jacket on the LTGES13B-A is black, which is the standard color for general purpose liquid tight and what most equipment whips on commercial roofs and in mechanical rooms already use. Gray and other colors exist in the category and are typically used to distinguish circuits, so if your facility standardizes on a color other than black, this coil will not match.
