Thomas & Betts 423 – Frequently Asked Questions
1) Is the Thomas & Betts 423 sleeve UL listed?
Yes. The 423 insulating sleeve carries UL file E23018 and is CSA recognized, which is what most facility and institutional specs want to see documented on an insulating bushing or sleeve.
2) How many Thomas & Betts 423 sleeves come in a pack?
They ship 25 to the inner carton and 100 to the outer, so a full master carton is 100 pieces. For MRO stocking, that is the unit to plan a shelf around.
3) What is the exact part number to order for the Thomas & Betts 3/4 inch insulating sleeve?
Order catalog number 423 from Thomas & Betts. There is a single model on it, so the only thing to confirm is the 3/4 inch trade size and the pack quantity you want.
4) How much does a box of 100 Thomas & Betts 423 insulating sleeves weigh?
About 0.5 lbs per 100 pieces. Carton footprints are 3x4x4 inches for the 25-count inner and 8.9x7x5 inches for the 100-count outer, so a full master carton is light and easy to stage on a van or a job cart.
5) What does an insulating sleeve like the T&B 423 actually do on a wiring job?
It lines the throat of a raceway or fitting so conductors bear on nylon instead of a metal edge. In practice you use one anywhere wire enters or leaves a metal opening and the insulation could be chafed by pulling or vibration. The 423 covers the 3/4 inch trade size.
