Thomas & Betts 424 – Frequently Asked Questions
1) What size conductor or wire does the Thomas & Betts 424 insulating sleeve fit?
The 424 is sized for a 1 inch nominal cross section, so it is the 1 inch sleeve in the Thomas & Betts insulating sleeve range. Match the sleeve to the nominal size of the connector or conductor you are covering rather than to the sleeve's own outside dimension.
2) What is the Thomas & Betts 424 sleeve made of, and is it listed?
Nylon body, carrying UL E23018 and CSA. That combination is what an electrical inspector or an MRO buyer standardizing on listed components looks for on an insulating sleeve.
3) How many Thomas & Betts 424 insulating sleeves come in a box or case?
Packed 25 to the inner carton and 100 to the outer case. Contractors buying for a single panel job typically take the 25 pack; distributors and facility stockrooms take the 100 case.
4) Is the Thomas & Betts 424 a heat shrink tube?
No. The 424 is a rigid nylon insulating sleeve that slips over the connection, not a heat shrink product. There is no torch or heat gun step, and it will not conform to the shape of the joint the way shrink tubing does. If you need a moisture seal that grips the conductor, choose heat shrink instead.
5) What part number do I order for the Thomas & Betts 1 inch nylon insulating sleeve?
Order it as Thomas & Betts 424. That is the manufacturer part number, and it is a single configuration item, no finish, length, or color to specify.
6) What are the carton dimensions and shipping weight for the T&B 424 sleeves?
The inner carton measures 6.2 x 4.7 x 4.3 inches and the outer measures 9.7 x 9.1 x 7.1 inches. Weight works out to 12.4 lbs per 1000 pieces, so a 100 piece outer is a light, easy-to-stock item on a service van or a shelf.
