2 inch Proflex Coupling Connects Copper to Cast Iron, PVC, Steel

2” Fernco ProFlex Shielded Coupling – Transition Fitting for Multi-Material DWV Systems

The 2” Fernco ProFlex Shielded Coupling is engineered to connect dissimilar piping materials—including cast iron, PVC, copper, and steel—in drainage, waste, and vent (DWV) applications. Its stainless steel shield and molded elastomeric sleeve combine to provide axial load resistance and a secure, code-compliant joint.

This coupling is frequently specified in remodels, system upgrades, and spot repairs where material transitions are required. Its design allows for mechanical flexibility while maintaining the structural requirements necessary for a permanent connection between varied pipe types.

Performance Features

• ✅ Shielded Construction Features a full-coverage 300-series stainless steel band to minimize shear and maintain alignment.
• ✅ High-Seal Compression Stainless steel clamps provide uniform pressure across the coupling, ensuring a leak-resistant seal at each interface.
• ✅ Multi-Material Adaptability Suitable for transitions between copper (Type DWV or L/M), no-hub cast iron, galvanized steel, and Schedule 40 PVC.
• ✅ Temperature and Pressure Resilience Designed to perform in a range of conditions typically found in gravity flow and low-pressure systems.

Technical Specifications

• Nominal Size: 2 inches
• Materials: Elastomeric PVC sleeve (ASTM C1173 compliant), stainless steel bands and shield (Type 301/304)
• Connection Type: Mechanical coupling with torque-band compression
• Compliance: Meets ASTM C1460, CSA B602, UPC/IAPMO Listed

Installation Guidelines

Install the coupling by positioning the rubber body over both pipe ends, aligning per pipe O.D. ranges, then securing the stainless steel bands using a calibrated torque wrench to the manufacturer-specified setting—typically 60 in-lbs unless otherwise noted. No solvent welding, threading, or adhesives are required. Always verify compatibility with local code for transition fittings.

Application Use Cases

Commonly installed in DWV system retrofits, vertical stack repairs, or lateral sewer updates. Especially effective in transition zones where original construction materials differ from updated system components. Not for pressurized potable water or gas systems.

Code and Industry Relevance

ProFlex couplings are widely accepted by plumbing inspection authorities due to their standardized performance and certified testing across multiple materials. Their design helps reduce vibration transmission and compensates for minor pipe deflection or misalignment.

The 2” Fernco ProFlex Shielded Coupling offers a durable, compliant solution for professionals working across mixed-material plumbing infrastructures. Its engineered design supports high-integrity jointing while streamlining installation in both new and existing systems.
