Conduit Nipple · 2-1/2 in Close - Threaded for Rigid/IMC - 2.5XCLOSE

What this product is for

This 2-1/2 in close conduit nipple is used to make a short threaded connection between rigid metal conduit (RMC) or IMC and an enclosure, conduit body, or threaded fitting where there is very little room for a longer nipple.

Use for

Use for threaded rigid or IMC conduit systems in commercial, industrial, and service installations. It is commonly used to join enclosures or fittings back-to-back, or where a standard nipple length would project too far.

Avoid for

Avoid using this item where EMT fittings are required, where a non-threaded connection is needed, or where the exact material, finish, or certification has not been confirmed for the job. If corrosion resistance is critical, confirm whether you need galvanized steel, zinc, aluminium, or stainless construction.

Best for

Best for tight-space threaded conduit terminations and short enclosure-to-fitting connections in rigid/IMC systems.

Installed in

Typically installed in electrical rooms, industrial facilities, commercial buildings, service equipment, and other threaded conduit applications using 2-1/2 in trade size raceway. 2-1/2 in trade size is approximately 63.5 mm.

Why this product exists

A close nipple provides the shortest practical threaded connection when electricians need to maintain alignment and minimise stand-off between threaded components.

Compared with similar products

Compared with standard-length nipples, a close nipple reduces projection and helps in cramped layouts. Compared with chase nipples, it is typically used where a fully threaded rigid/IMC connection is needed. Selection should be based on trade size, thread type, material, and listing. Actual fit depends on the connected fittings and thread engagement.
