Thomas Betts TCF075 40 Al Strain Relief Cord Grip 3/4 Npt

Product Description

The THOMAS BETTS TCF075 40 AL is a straight strain relief cord grip designed for use in Class 1 gas and vapor environments. Built from aluminum, this fitting accepts cables ranging from 0.25 to 0.4 inches in diameter and threads directly into a 3/4-inch NPT conduit entry. It secures conductors at the point of entry into an enclosure or junction box, preventing pull-out and protecting the cable jacket from abrasion or mechanical stress. Licensed electricians install this fitting as part of a compliant conduit system where flammable gas or vapor may be present.

This cord grip is suited for industrial and commercial electrical installations where Class 1 hazardous location ratings are required. Typical applications include control panels, motor junction boxes, and enclosures installed in environments with potential exposure to flammable gases or vapors. The straight-body configuration allows for direct inline entry without angled clearance requirements. The 3/4-inch NPT thread is a common conduit size found across a wide range of enclosures, making this fitting a practical stock item for service electricians and panel builders.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 501 requirements for Class 1 hazardous locations. De-energize the circuit and verify the enclosure is rated for the hazardous location classification before beginning work. Thread the fitting into the NPT entry and tighten to ensure a secure, gas-tight seal. Do not overtighten aluminum fittings, as this may damage the threads or distort the fitting body.
