Thomas & Betts 222-TB – Frequently Asked Questions

1) What thread sizes do the Thomas & Betts insulated bushings come in?
Two sizes: the 222-TB is the 1/2 inch and the 223-TB is the 3/4 inch. Both thread onto standard NPT conduit ends and enclosure hubs, so you order by the trade size of the conduit or fitting you are protecting.
2) Is this insulated bushing UL Listed for commercial electrical work?
Yes. The Thomas & Betts insulated bushing carries UL file E23018 and is CSA certified, which is what an inspector looks for on a commercial or industrial conduit termination.
3) Does a plastic bushing satisfy the requirement to protect conductors at a conduit end?
That is exactly the job of it. The molded plastic body insulates the cut metal edge of the raceway or fitting so conductors are not chafed as they are pulled or as they vibrate in service. Material is plastic, and the part is UL E23018 and CSA recognized for electrical use.
4) Is this a threaded bushing or a snap-in type?
Threaded. It is made for 0.5 NPT thread applications, so it screws onto the male thread of a conduit end or fitting rather than snapping into a plain knockout. If you have an unthreaded punched knockout, you want a snap-in style bushing instead.
5) How many insulated bushings come in a box?
They are packed in bulk, 100 pieces to an inner carton and 400 to the outer case. For MRO stockrooms or a rough-in crew running a lot of half-inch pipe, the 100-count inner is the practical shelf unit.
6) What is the outside diameter of the 1/2 inch insulated bushing?
26.98mm across the outside, which is what decides whether it clears adjacent fittings or a crowded knockout pattern in a panel or junction box.
7) What part number do I order to match existing 3/4 inch conduit fittings?
Ask for Thomas & Betts 223-TB for 3/4 inch. The matching half-inch part is 222-TB, so a facility standardizing on both sizes carries the two numbers together.
8) Can I use these plastic insulated bushings outdoors or in a wet location?
Treat them as insulating protection, not a seal. The plastic body resists environmental exposure, but nothing in the specification rates the part for wet or damp location sealing, so use a listed sealing or liquidtight fitting where the enclosure rating has to be maintained.
