SEPCO 90Z Zinc Die-Cast Hex Head Chase Nipple, Non-Insulated Throat

The SEPCO 90Z Series chase nipple is built from rugged zinc die-cast construction, giving electrical contractors a durable connector for joining conduit bodies and enclosures back-to-back within tight raceway layouts. This hex head chase nipple features a non-insulated throat and is available across trade sizes from 1/2" through 4" to match the fit needed for conduit-body, box, and enclosure connections. Solid zinc die-cast construction delivers corrosion resistance and long-term strength for demanding commercial and industrial electrical work, and the hex head profile makes torque control simple with standard hand tools during installation.

SEPCO 90Z – Frequently Asked Questions

1) What is a chase nipple used for, and how is it different from a regular conduit nipple?
A chase nipple like the SEPCO 90Z is a short, male-threaded fitting with a hex head that joins two conduit bodies, boxes, or enclosures back-to-back where there is almost no space between them. It threads into one enclosure hub and a locknut secures it on the other side. A standard conduit nipple is a longer running thread or close nipple used to span a gap; the chase design exists for the tight, flush case where a long nipple will not fit. If you need a corrosion-resistant run-length nipple instead, the Ocal NPL1X4-G is a 1 inch x 4 inch PVC-coated conduit nipple.
2) What trade sizes does the SEPCO 90Z chase nipple come in?
Eight trade sizes are offered: 1/2 inch (90Z), 3/4 inch (91Z), 1 inch (92Z), 1-1/4 inch (93Z), 1-1/2 inch (94Z), 2 inch (95Z), 2-1/2 inch (96Z) and 4 inch (99Z). Order by the trade size of the enclosure hub or conduit body opening you are threading into, not by the conductor fill.
3) Is the SEPCO 90Z chase nipple safe to use where conductors pull through it?
The 90Z has a non-insulated throat, so there is no plastic or nylon bushing protecting the conductor at the opening. Where an insulated throat is called for on the job, specify an insulated-throat fitting or add a separate insulating bushing. For standard back-to-back enclosure joints with no conductor abrasion concern, the non-insulated version is the normal choice.
4) Is the SEPCO 90Z the right fitting for joining two junction boxes mounted flush against each other?
That is exactly the case it is built for. The short-body chase profile lets you make a threaded joint between two enclosures or conduit bodies sitting back-to-back with essentially no gap, which a longer nipple cannot do. Match the trade size to the existing hub openings, available 1/2 inch up to 4 inch.
5) What should I use instead of a SEPCO 90Z chase nipple in a corrosive wash-down or chemical area?
The SEPCO 90Z is a zinc die-cast hex head chase nipple, which covers general commercial and industrial raceway work. Where the environment calls for a coated fitting, the Ocal NPL1X4-G is a PVC-coated, corrosion-resistant conduit nipple in a 1 inch by 4 inch size. Note that the two are not the same joint: the 90Z is a short chase nipple for joining two conduit bodies or enclosures back-to-back, while the Ocal piece is a 4 inch long nipple used to span between fittings.
6) Will a zinc die-cast chase nipple hold up in a damp or corrosive area?
The 90Z body is zinc die-cast, which gives decent corrosion resistance for general commercial and industrial raceway work indoors and in normally dry or occasionally damp locations. For chemically aggressive or wash-down environments, a PVC-coated fitting is the better call; the Ocal NPL1X4-G is a PVC-coated, corrosion-resistant conduit nipple in 1 inch x 4 inch.
7) Do I need a locknut with a SEPCO 90Z chase nipple, or is one included?
A chase nipple threads into a tapped hub on one side and needs a locknut on the other side to clamp through the sheet metal of the second enclosure. The 90Z is sold as the nipple itself by trade size, so order locknuts in the matching size separately, plus a sealing or insulating bushing if your spec calls for one.
8) Can I substitute an Ocal NPL1X4-G for the 1-inch SEPCO 90Z chase nipple?
Not as a direct swap. The 1 inch trade size in the SEPCO 90Z family is part number 92Z, a short chase nipple that pulls two enclosures or conduit bodies together in a tight footprint. The Ocal NPL1X4-G is a 1 inch by 4 inch PVC-coated conduit nipple, so the trade size matches but the length does not - it will stand the two fittings 4 inches apart rather than joining them back-to-back.
9) For a 2-inch or larger back-to-back enclosure connection, which nipple fits?
The SEPCO 90Z chase nipple runs through the larger trade sizes, including 2 inch (95Z), 2-1/2 inch (96Z) and 4 inch (99Z), all in the same zinc die-cast hex head form. The Ocal NPL1X4-G is a 1 inch size, so it does not cover those larger openings.
10) Can I tighten a 90Z chase nipple with a standard wrench?
Yes. The hex head profile takes an open-end or adjustable wrench, so you get real torque control instead of trying to grip a round body with pliers. That matters on the larger 2-1/2 inch and 4 inch sizes, where a hand-tight joint will not stay put.
