Thomas & Betts 8421 – Frequently Asked Questions
1) Is the Thomas & Betts 8421 connector metal or plastic?
Malleable iron is the body material on the T&B 8421 threadless connector, not die cast zinc and not plastic. Malleable iron takes the clamping load without cracking, which is why it shows up on threadless fittings that grip conduit with a compression action rather than threads.
2) Why use a threadless connector instead of a threaded one on 1-1/4 inch conduit?
A threadless fitting like the T&B 8421 clamps onto the conduit end, so you skip cutting threads in the field. That is the reason it gets specified on retrofit and repair work where the existing run is already cut to length or where there is no room to swing a threader. If the run is being built new from threaded rigid, a threaded fitting is the simpler call.
3) How many Thomas & Betts 8421 connectors come in a box?
The 8421 is sold as a 100 pack, one carton of a hundred 1-1/4 inch threadless connectors. For an MRO crib or a contractor stocking a multi-building job that is a full bin quantity, not a job-lot of a few.
4) What is the manufacturer part number for the Thomas & Betts 1-1/4 threadless connector?
Order it as T&B 8421. That is the manufacturer part number as well as the catalog model, so a distributor or a purchasing desk cross referencing it will find the same number on both sides.
