Thomas & Betts 150ERB 3/4 IN X 6 FT CARFLEX KIT COIL

The 150ERB Carflex kit coil is 3/4 inch trade size liquidtight flexible conduit in a 6 foot coil. One coil per kit, ordered as model 150ERB.

Nonmetallic. The 150ERB is PVC liquidtight flexible conduit, so it carries no integral grounding path the way steel-core liquidtight does. Run an equipment grounding conductor inside the raceway.

Yes, 3/4 inch liquidtight flexible nonmetallic conduit is the common choice for the short flexible run into an HVAC condensing unit or similar outdoor equipment, and the 6 foot coil length suits a typical whip from disconnect to unit. Because it is PVC, pull a separate ground conductor with your circuit conductors.

It is sold as a kit coil, not bare conduit by the foot. For connections you need liquidtight connectors sized for 3/4 inch conduit at each termination, matched to the knockout size on your box or disconnect.

They serve the same role, a flexible liquidtight connection to equipment, but differ in one key way: this Carflex is PVC and nonmetallic, so it will not act as an equipment ground and needs a grounding conductor run inside. Metallic liquidtight with a steel core and a listed connector can serve as a ground path in some installations and holds up better where the run is subject to physical abuse. Choose nonmetallic where corrosion resistance and lighter weight matter.
