3 inch No Hub Soil Coupling

Matco-Norca 3-Inch No Hub Soil Coupling – Built for Dependable DWV Systems

The 3" no hub soil coupling from Matco-Norca is engineered for secure, leak-resistant connections in drain, waste, and vent (DWV) systems. Constructed to meet the rigorous demands of commercial and residential installations, this coupling simplifies alignment between cast iron no hub pipe and fittings while maintaining long-term reliability.

Performance Features

• ✅ Stainless Steel Shield Heavy-duty clamp assembly with stainless steel bands and shield for uniform compression and added corrosion resistance.
• ✅ Neoprene Gasket ASTM C564-certified neoprene provides excellent sealing and vibration dampening properties.
• ✅ Uniform Pressure Distribution Precision screw housings maintain consistent torque and prevent point loading, reducing deformation at joints.
• ✅ Tool-Free Alignment Designed for quick orientation and adjustment during installation with minimal setup time.

Technical Specifications

• Size: 3-inch nominal pipe size
• Material: Stainless steel shield, neoprene gasket
• Standards: Meets ASTM C1277 and CISPI 310 requirements
• Application: No hub cast iron DWV systems

Installation Guidance

This coupling is designed for use with torque-limiting wrenches set to 60 in-lbs per standard no hub coupling guidelines. Use is typically reserved for non-pressure applications and should comply with local code requirements, including applicable testing protocols under hydrostatic or pneumatic conditions.

Applications in the Field

Primarily used in multi-story residential and commercial construction, this fitting is essential for vertical and horizontal DWV runs. It’s particularly suited for transition areas such as floor penetrations or inter-floor stacks where vibration and joint stability are critical.

Code & Compliance Insight

All Matco-Norca no hub couplings are manufactured to comply with ASTM and CISPI standards and are approved for use in sanitary and storm drainage systems under the IPC and UPC model codes.

Count on the Matco-Norca 3-inch no hub soil coupling for a code-compliant, jobsite-proven solution that simplifies your DWV layouts while maintaining leak-resistant performance across the lifespan of the system. 🔧💪
