Electrical Coupling for EMT Conduit

The Hubbell RACO 2922 is a compression coupling built to join two lengths of 1/2 in electrical metallic tubing. It is intended for electricians and installers who need a secure, straight-line connection in commercial or residential wiring projects.

Capacity and Installation Limits

The coupling measures 1 29/32 in overall length with a 1 in by 1 in profile and weighs .12 lb. Its zinc-plated steel body provides concrete-tight performance for EMT raceways, but it does not accommodate larger trade sizes or non-EMT conduit types.

Upgrade Path and Compatibility

This fitting replaces worn or damaged couplings in existing 1/2 in EMT runs and upgrades from set-screw models where a compression seal is required. The jump is worthwhile when a concrete-tight, cULus-listed connection is specified by code.

Highlights

  • Compression coupling joins EMT conduit securely
  • Zinc-plated steel resists corrosion in damp locations
  • cULus listing confirms code-compliant installation
  • Concrete-tight seal protects wiring in slab pours
  • Compact 1 in profile fits tight junction boxes

Questions about this item

Will the 1/2 in trade size and straight connection orientation let me join existing EMT conduit runs without changing the layout?

The coupling is built for 1/2 in EMT and has a straight orientation, so it connects two conduit sections end-to-end in the same line without requiring bends or offsets.

How can I confirm the coupling is properly secured after installation?

Tighten the compression nuts until the conduit cannot rotate or pull out, then verify the zinc-plated steel body sits flush with no visible gaps at either end.

Does the RACO 2922 include the compression rings and locknuts, or must they be purchased separately?

The coupling ships with its integral clamp components; no additional rings or locknuts are required for a standard EMT compression connection.
