A 3-inch zinc-alloy compression connector that grounds EMT conduit, CSA-certified and UL-listed, weighing 1.31 lb

  • CSA Certified and UL Listed for code-compliant installations
  • Zinc alloy construction resists corrosion in damp locations
  • Compression design secures EMT conduit without threading tools
  • Concrete-tight rating protects connections in slab pours
  • 31 lb weight allows single-person handling on site

RACO 2842 EMT Grounding Connector 3 in

This RACO 2842 is a compression-type grounding connector for 3-inch EMT conduit. It is made from zinc alloy with a plain gray finish and carries CSA certification and UL listing. The fitting provides a straight, threaded connection that is concrete-tight.

Suitable for electricians running 3 in EMT

Installers who need a code-compliant, concrete-tight transition for 3-inch EMT will find this connector matches the spec. It is not insulated, so projects requiring an insulated throat should select a different fitting.

3 in trade size with NPS threads

The connector fits 3-inch EMT trade size and uses 3 In.-8 NPS threads. This single dimension determines whether it matches the conduit and the threaded opening on the enclosure.

Questions about this item

How is the RACO 2842 compression connector installed on 3 in EMT, and what step is often missed?

Thread the connector onto the conduit using the 3 In.-8 NPS threads, then compress the fitting with a dedicated 3 in compression tool; the step often missed is fully tightening the compression ring to achieve the concrete-tight seal.

What maintenance or replacement will the zinc alloy connector need over time?

The plain gray zinc finish has no insulated coating, so inspect periodically for corrosion or thread damage; replace the fitting if the compression ring no longer seats tightly or if the NPS threads show galling.

What limit appears first during sustained use of this EMT grounding connector?

The 1.31 lb zinc body relies on mechanical compression for conductivity; sustained vibration or thermal cycling can loosen the ring, increasing resistance at the joint before the conduit itself degrades.
