Conduit Nipple for IMC Systems

This 1/2 in threaded aluminium nipple connects two sections of IMC or threaded rigid metal conduit in hazardous locations. It carries Class I Division 1 and 2 ratings for Groups A through D, Class II Division 1 and 2 for Groups E through G, and Class III Division 1 and 2. The powder-coated finish adds corrosion resistance in demanding environments.

Threaded Interface and Length Constraints

The fitting uses male NPT threads on both ends with an overall length of 1 1/2 in. This fixed length limits the gap between conduit runs and cannot be adjusted in the field. Installers must verify that the thread engagement meets code requirements for the specific hazardous classification and that the conduit alignment accommodates the nipple's rigid dimensions.

Pre-Installation Verification Checklist

Confirm that your existing conduit is IMC or threaded rigid metal conduit in the 1/2 in trade size before ordering. Verify that the hazardous location classification of the installation matches the fitting's approved ratings. Ensure the available space allows for the 1 1/2 in overall length and that the mounting orientation suits the 3/4 in height and width profile.

Questions about this item

Should I pick the 1/2 in trade size or a different size for my IMC conduit?

This nipple is made for 1/2 in IMC and threaded RMC only; match it to conduit of the same trade size.

What does the 1 1/2 in overall length mean when the nipple is installed?

It adds 1 1/2 in between the two enclosures or fittings you are joining, so plan your conduit run accordingly.

How do the 1/2 in MNPT threads affect what I can connect?

Both ends are 1/2 in male NPT, so they screw directly into female-threaded hubs, boxes or couplings rated for the same size.
