Frequently Asked Questions

What is the RACO Compression Coupling used for?

The RACO Compression Coupling connects two lengths of rigid metal conduit (RMC) in electrical raceway systems. Its concrete-tight design prevents moisture and debris ingress, making it suitable for embedded or exposed industrial, commercial, and infrastructure installations where conduit joints must remain sealed.

What are the specifications of the RACO Compression Coupling?

This steel compression coupling has a 1/2-inch trade size, 1 13/32-inch overall length, and is compatible with RMC conduit. It is concrete-tight rated, with manufacturer part number 1822. The RACO brand ensures dimensional consistency for secure, code-compliant connections in electrical 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 RACO part to any international destination.

How to install a RACO Compression Coupling on RMC conduit?

Slide the coupling onto the first conduit end, insert the second conduit, then tighten the compression nut with a wrench until the joint is snug and concrete-tight. Avoid over-tightening to prevent thread damage. Always follow NEC guidelines and use proper supports for embedded or exposed runs.

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.
