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.
