Thomas & Betts 5355 – Frequently Asked Questions

1) What trade size liquid tight flexible conduit does the Thomas & Betts 5355 connector fit?
The T&B 5355 is a 1-1/4 inch trade size connector, so it terminates 1-1/4 inch liquid tight flexible metal conduit and threads into a 1-1/4 inch knockout or hub. It will not adapt other trade sizes, so size the fitting to the conduit run rather than to the enclosure opening.
2) When should I use a 90 degree liquid tight connector instead of a straight one?
Use the 90 degree version when the conduit has to turn immediately at the box, panel, or motor, and there is no room for a straight fitting plus a sweeping bend in the flex. The 5355 makes that turn at the fitting itself, which keeps the conduit off the wall and avoids kinking the liner. If you have clearance for the flex to curve on its own, a straight connector is the simpler termination.
3) Will this connector keep water out of the panel on an outdoor or washdown installation?
The 5355 is a liquid tight fitting, so with the sealing ring compressed against the enclosure and the gland tightened on the conduit jacket it seals the termination against moisture, dust, and contaminants. It only performs that way if the mating enclosure and knockout are themselves rated for the location; a liquid tight fitting on a plain indoor box does not make the box weatherproof.
4) Does this fitting provide strain relief, or do I still need a separate cable clamp?
Strain relief is built in. The gland clamps the conduit jacket so mechanical load and vibration are taken by the fitting rather than by the conductor terminations inside the box, which is why these get specified on motors, HVAC units, and moving machinery. No separate clamp is needed for the conduit itself.
5) What is the exact part number to order for the Thomas & Betts 1-1/4 inch insulated 90 degree liquid tight connector?
Order Thomas & Betts 5355. That is the manufacturer part number for the 1-1/4 inch insulated 90 degree liquid tight connector in malleable iron, and it ships as a single fitting rather than as a kit with a locknut assortment.
6) What does the insulated throat on this liquid tight connector actually do for me?
The insulated throat protects conductor insulation as wires are pulled through the fitting, which matters on a 1-1/4 inch connector where you are typically pulling several current-carrying conductors at once. It reduces the chance of nicking insulation on the metal edge of a malleable iron body during the pull.
7) Can I use this on a control panel or HVAC unit connection, or is it only for conduit-to-box runs?
Both. It is used on industrial control panels and electrical enclosures, HVAC equipment connections, manufacturing and process automation equipment, commercial building systems, and outdoor and harsh-environment installations. Anywhere 1-1/4 inch liquid tight flex needs to enter an enclosure at a right angle is the application.
