Thomas Betts 255 Fmc Conduit Connector 3/4 Inch Steel

Product Description

The THOMAS BETTS 255 is a straight, non-insulated conduit connector designed for use with flexible metal conduit (FMC). It uses a squeeze clamp connection method to secure the conduit end at the enclosure or box entry point. Constructed from steel, this connector is rated for hazardous location applications, making it suitable for industrial and commercial electrical installations where environmental conditions demand durable, code-compliant fittings. The 3/4 inch trade size fits standard FMC of that diameter. Licensed electricians and electrical contractors install this fitting as part of branch circuit and equipment wiring runs.

This connector is intended for use with 3/4 inch FMC in both commercial and industrial settings, including hazardous location environments where steel construction and reliable mechanical connection are required. Typical installation scenarios include connecting flexible conduit to junction boxes, enclosures, motor termination points, and control panels. Its straight profile suits direct, in-line entries where no angle offset is needed.

Compatibility

Designed for use with 3/4 inch trade size flexible metal conduit (FMC). Suitable for hazardous location installations where FMC termination at enclosures or junction boxes is required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the circuit and lock out the panel before beginning conduit termination work. Insert the FMC end into the connector and tighten the squeeze clamp securely to ensure proper mechanical and electrical continuity. Verify the knockout size matches the 3/4 inch trade size of this connector before installation.
