Thomas & Betts 5331 – Frequently Asked Questions

1) What trade sizes does the Thomas & Betts insulated liquid-tight straight connector come in?
Three trade sizes: 3/8 inch (part 5331), 1/2 inch (part 5332), and 1 inch (part 5334-TB). Order by the trade size of the liquid-tight flexible conduit you are terminating, not by the wire size inside it.
2) Can I use this connector on a wet location or outdoor motor connection?
That is what it is built for. It is a liquid-tight straight connector for terminating liquid-tight flexible conduit into enclosures and junction boxes, and it maintains the seal in wet, washdown, and outdoor conditions. Common uses are motor leads, control panels, and equipment connections where the conduit is exposed to moisture.
3) Will a 1/2 inch liquid-tight connector work with 1/2 inch flexible metal conduit that is not liquid-tight?
No. These are sized and sealed for liquid-tight flexible conduit, which has a jacket over the core. Standard flexible metal conduit (Greenfield) takes its own squeeze or screw-in connector. Match the connector to the conduit type, then to the trade size: 3/8, 1/2, or 1 inch here.
4) What does the insulated part of an insulated liquid-tight connector actually do?
The insulated throat gives electrical isolation at the point where the conductors pass out of the connector, so the wire jacket is not bearing against a bare steel edge as it enters the box. On this Thomas & Betts connector the body itself is steel, with the insulation at the conductor opening.
5) Does this connector provide strain relief for the cable, or just terminate the conduit?
Both. It is a strain relief connector, so once tightened it grips the liquid-tight conduit and keeps mechanical stress and movement off the conductors and their terminations inside the enclosure. That matters on vibrating equipment like motors and on flexible drops that get pulled on.
6) Is a steel liquid-tight connector better than a die cast one for industrial work?
Steel is the choice where the fitting takes physical abuse. This Thomas & Betts connector is steel bodied, which holds up to impact and keeps dimensional stability under load better than lighter cast bodies, so it suits manufacturing floors, processing plants, and equipment connections that get knocked around.
