Frequently Asked Questions

What is the RACO Compression Coupling used for?

The RACO Compression Coupling is used to join two lengths of RMC (Rigid Metal Conduit) in electrical installations. Its concrete-tight design prevents moisture and debris ingress, making it suitable for embedded or exposed conduit runs in industrial, commercial, and infrastructure projects.

What are the specifications of the RACO Compression Coupling?

This RACO Compression Coupling has a 1-inch trade size, 1 11/16-inch overall length, and is made of steel. It is compatible with RMC conduit and is rated concrete-tight (MPN 1824). The coupling provides a secure, threaded compression connection for rigid conduit systems.

Where to buy the RACO Compression Coupling worldwide?

3G Electric supplies the RACO Compression Coupling worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this coupling to any international destination.

How to install a RACO Compression Coupling?

To install, thread the coupling onto the end of one RMC conduit section, then insert the second conduit end and tighten the compression nut with a wrench until secure. Ensure the joint is concrete-tight by verifying full engagement. Follow standard electrical conduit practices for torque and alignment.

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.
