Thomas & Betts 842-TB – Frequently Asked Questions
1) What trade sizes does the Thomas & Betts chase nipple come in?
Two trade sizes: 1/2 inch (part 842-TB) and 3/4 inch (part 843-TB). Pick the size to match the conduit trade size and the knockout it is going into, not the measured hole diameter.
2) Will the 842-TB chase nipple fit a 1/2 inch knockout in a steel box?
Yes. The 842-TB is built for a 1/2 inch trade size knockout and threads through it, with the locknut drawn up on the opposite side to bond and secure it. For a 3/4 inch knockout you need the 843-TB instead.
3) Is this an insulated throat chase nipple?
No. Both the 842-TB and 843-TB are non-insulated. If the job calls for an insulated throat on the conductor entry, this is the wrong part and you want the insulated version of the chase nipple in the matching trade size.
4) What is a chase nipple used for in conduit work?
A chase nipple joins a conduit run or fitting through a sheet metal enclosure wall, usually box to box or box to fitting, where there isn't room for a full coupling and locknut assembly. The Thomas & Betts 842-TB is the non-insulated 1/2 inch version: short male threaded body that passes through a knockout and takes a locknut on the far side. Non-insulated means there is no throat liner, so it is intended for use where an insulated throat isn't required by the installation.
5) Does the chase nipple come with a locknut?
The 842-TB is the nipple body itself. A chase nipple installation needs a locknut on the back side of the enclosure wall to draw the joint tight, so order locknuts in the matching 1/2 inch or 3/4 inch trade size along with the nipples.
6) What part number do I order for a 3/4 inch non-insulated chase nipple from Thomas & Betts?
843-TB is the 3/4 inch non-insulated chase nipple. The 1/2 inch is 842-TB. Those are the manufacturer part numbers to quote when matching an existing install.
