Killark AN-3 IMC Conduit Nipple

The Killark AN-3 is a 1-inch threaded aluminum conduit nipple designed for IMC and threaded rigid metal conduit systems. It provides a male-to-male connection in hazardous-location electrical installations. The plain silver finish suits industrial and commercial environments.

Hazardous-location electrical contractors

This nipple suits contractors joining two female-threaded conduit ends in Class I, II and III hazardous areas where explosion-proof fittings are required. It is not for buyers who need a female-threaded fitting, a larger trade size or a non-hazardous-rated coupling.

One-inch trade size headroom

The 1-inch trade size handles standard IMC and rigid conduit runs in the specified hazardous classes. It runs out when the installation calls for a different trade size, a female thread profile or a fitting rated beyond the listed hazardous-location classes.

Questions about this item

What trade-size conduit must I already have to thread this 1 in nipple onto?

You need 1 in IMC or threaded rigid metal conduit so the male NPT ends engage correctly.

Can I join this aluminum nipple to existing steel rigid conduit in the same run?

Yes, the 1 in MNPT threads match standard rigid conduit threads, but dissimilar metals may require a transition fitting per local code.

How do I confirm the nipple is seated properly after installation?

Verify both male threads are fully engaged, the 1 31/32 in overall length spans the gap, and the hazardous-location rating markings face the inspector.
