RACO 1514 IMC Coupling for Conduit Systems

The RACO 1514 is a three-piece threaded coupling made from iron with a plain gray finish. It connects trade size 3-1/2 inch IMC or RMC metallic conduit in straight runs. The fitting uses NPT female threads on both ends and carries cUL certification for electrical installations.

Upgrade from damaged or non-compliant couplings

Replace worn, corroded or unlisted couplings with this cUL listed fitting when conduit threads are stripped or when code requires a listed three-piece design. The jump is worth it during service upgrades or when pulling new conductors through existing raceways that need a secure, code-compliant joint.

Handles 3-1/2 inch trade size conduit runs

This coupling accommodates IMC and RMC conduit at the 3-1/2 inch trade size with an overall length of 3-1/2 inches and overall height and width of 5-3/16 inches. It runs out when the conduit system requires a different trade size, a set-screw or compression connection, or a fitting rated for hazardous locations.

Questions about this item

What thread size does the 1514 coupling use for IMC conduit?

It uses a 3-1/2 inch NPT female thread on both ends for straight connection.

How many pieces make up this coupling and what orientation is required?

It is a three-piece straight coupling; tighten all sections evenly to avoid cross-threading the iron threads.

When should the gray plain-finish iron coupling be inspected or replaced?

Check for corrosion or thread damage after any conduit impact or if the 6.02 lb fitting shows movement.
