Thomas & Betts 1943 – Frequently Asked Questions

1) What is a chase nipple used for in a conduit run?
A chase nipple is the short threaded fitting that carries a conduit connection through a wall, floor, or enclosure and joins it to the run on the other side. The Thomas & Betts 1943 is the 3/4 inch trade size version, made of malleable iron, with an insulated throat so conductors pulled through the opening are not dragged over bare metal. Electricians reach for it at panel and box penetrations where two runs have to meet through a structural surface rather than be coupled in open air.
2) Does the Thomas & Betts 1943 chase nipple have an insulated throat, and why does that matter for pulling wire?
Yes, the 1943 is the insulated version. The insulating surface at the throat keeps conductor insulation off the bare metal edge of the fitting during the pull and in service, which is the reason inspectors and electricians specify an insulated chase nipple over a plain one on circuits where the conductors bear against the opening. If the job spec just calls for a chase nipple with no insulation requirement, a plain nipple does the same mechanical job, but the insulated one is never wrong in its place.
3) Will a 3/4 inch chase nipple fit a 3/4 inch knockout in a panel or junction box?
Yes. The 1943 is 3/4 inch trade size, which is the same designation used for knockouts, conduit, and locknuts, so it lands in a standard 3/4 inch knockout and takes a 3/4 inch locknut on the far side. Trade size is a system designation, not a measured diameter, so match the marking on the box or conduit rather than a tape measure reading.
4) Is a chase nipple the same thing as a conduit coupling or a close nipple?
No, and the difference decides the order. A coupling joins two lengths of conduit end to end in open air. A close nipple is a short length of threaded conduit, threaded the whole way, used to bridge two fittings. A chase nipple like the 1943 is made to pass through a wall, floor, or enclosure surface and be secured with a locknut on the opposite side, which is why it has the short body and shoulder it does. If nothing is being penetrated, a chase nipple is the wrong part.
5) Is the Thomas & Betts 1943 chase nipple steel or die cast, and how does it hold up in a damp mechanical room?
Malleable iron, not zinc die cast. That is the heavier of the two common constructions for this fitting and it takes mechanical abuse from wrench torque and from conduit being leveraged during a pull without cracking the way a cast fitting can. For MRO and industrial buyers standardizing a stockroom, malleable iron is the construction usually specified for plant and mechanical room work.
6) Do I need to order a locknut separately with a Thomas & Betts 1943 chase nipple?
Plan on it. The 1943 is supplied as the chase nipple itself, and a through-wall or through-enclosure installation is made up with a 3/4 inch conduit locknut on the opposite side of the surface to draw the fitting tight. Order the locknut in the same trade size, 3/4 inch, and in the same quantity as the nipples.
7) What is the manufacturer part number for the Thomas & Betts 3/4 inch insulated chase nipple?
The part number is 1943, from Thomas & Betts, for the 3/4 inch insulated chase nipple in malleable iron. That is the number to quote on a purchase order or to a counter, and it is the single model this fitting is sold under, so there is no size or finish suffix to add.
