Technical Specifications
This 1-1/4" trade size compression coupling features malleable iron construction with precision-machined compression rings for secure conduit connections. Compatible with both rigid steel conduit and intermediate metal conduit (IMC) systems, the coupling measures 2.63" in length with a 2.38" diameter profile. Weighing 0.85 pounds, the robust construction provides superior mechanical strength while maintaining compact installation dimensions. The compression design eliminates the need for conduit threading while ensuring reliable electrical continuity and grounding performance.
Installation Process
- Verify conduit ends are cut square and deburred for proper seating
- Slide compression coupling onto first conduit end until fully seated
- Insert second conduit end into opposite side of coupling
- Tighten compression nuts evenly using appropriate wrenches
- Verify secure mechanical connection and proper alignment
- Test electrical continuity if required for grounding verification

Compression Coupling System Benefits
Compression couplings provide superior installation flexibility compared to threaded connections by eliminating the need for precise conduit threading. This design allows for easier alignment corrections during installation while maintaining secure mechanical and electrical connections. The compression mechanism distributes stress evenly around the conduit circumference, reducing the risk of conduit deformation or connection failure under thermal expansion and mechanical stress.
Why Choose Malleable Iron Construction?
Malleable iron offers superior strength and impact resistance compared to standard steel fittings, making it the preferred choice for demanding electrical installations. This material provides enhanced dimensional stability under temperature variations while maintaining excellent machinability for precision threading. The malleable iron construction ensures long-term reliability in high-stress applications, reducing maintenance requirements and providing decades of dependable service in commercial and industrial electrical systems.
