Frequently Asked Questions

What is a RACO Threaded Coupling used for?

A RACO Threaded Coupling connects two lengths of IMC conduit in industrial electrical installations. This three-piece iron coupling provides a secure, threaded joint for routing and protecting wiring in commercial and industrial environments.

What are the specifications of the RACO 1506 coupling?

The RACO 1506 is a three-piece threaded coupling made of iron. It has a 1 1/2 in trade size, 2 1/4 in overall length, and is compatible with IMC conduit. The manufacturer part number is 1506.

Where to buy RACO threaded couplings worldwide?

3G Electric supplies RACO threaded couplings worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver the RACO 1506 and other conduit fittings to your facility, wherever it is located.

How to install a three-piece threaded coupling on IMC conduit?

To install a RACO three-piece coupling, thread the coupling onto the first conduit length, then thread the second conduit into the opposite end. Tighten the center ring to lock the joint. Use a wrench for a secure fit without over-tightening.

Used in

Common applications for RACO
Industrial machinery — RACO liquid-tight connectors (e.g., 3520-3, 3414) terminate flexible metallic conduit at motor and control enclosures.
Water and wastewater treatment — RACO 90-degree liquid-tight connectors (e.g., 3430) route conduit in washdown and outdoor areas requiring liquid-tight terminations.
Commercial electrical raceways — RACO short elbows (e.g., 1/2 in and 3/4 in iron elbows) change direction in IMC and RMC runs per UL 514B.
Panel and equipment wiring — RACO flex screw-in couplings (e.g., 2272) join sections of 1/2 in flexible conduit between machines and junction points.
Raceway transitions — RACO flex-to-EMT couplings (e.g., 1482, 1483) connect flexible conduit to EMT in mixed raceway installations.
Maintenance and repair — RACO conduit fittings and boxes are stocked as spares for replacing damaged terminations and couplings in existing raceways.
