RACO 1516 IMC Coupling 4-Inch

This RACO 1516 coupling joins two sections of threaded metallic conduit. The three-piece iron body is zinc plated for corrosion resistance and finished in gray. It accepts IMC and RMC conduit types with a trade size of 4 inches. The fitting carries a cUL listing for code-compliant installations.

Suits installers joining 4-inch IMC or RMC runs

Electricians needing a straight female-to-female NPT connection for 4-inch threaded conduit will find this part fits the requirement. The three-piece design allows assembly without turning the conduit itself. Installers working with EMT, PVC or smaller trade sizes must select a different fitting.

Three-piece iron construction with NPT threads

The coupling uses a three-piece iron housing with female NPT threads on both ends. This construction permits installation where conduit cannot be rotated. The zinc-plated gray finish protects the iron substrate in damp or outdoor locations.

Highlights

  • Three-piece design simplifies conduit connections
  • NPT female threads join IMC and RMC securely
  • cUL listing confirms safety compliance
  • Zinc-plated iron resists corrosion in harsh environments
  • 24 lb weight indicates robust construction

Questions about this item

Does the RACO 1516 coupling include locknuts or bushings, or must they be purchased separately?

The three-piece coupling connects two threaded conduit ends directly. Locknuts and bushings are not included and must be bought separately for a complete installation.

When should I choose this 4-inch trade-size coupling instead of a smaller size?

Select this coupling when joining 4-inch trade-size IMC or RMC conduit. The 4 in.-8 NPT female threads match that conduit size; smaller conduit requires a different trade-size fitting.

What does the 7.24 lb weight mean for handling and support during installation?

At 7.24 lb the iron coupling is heavy enough to need firm support while threading. Plan for mechanical assistance or a second person when mounting overhead or in tight spaces.
