2 inch x 1-1/2 inch Proflex Reducing Coupling Connects Copper to Cast Iron, PVC, Steel

Fernco 3001-215 ProFlex Shielded Coupling – 2" x 1-1/2" Transition for DWV and Sewer Systems

The Fernco 3001-215 ProFlex Shielded Coupling is a code-compliant, mechanical transition fitting used for joining 2" to 1-1/2" nominal piping in drainage, waste, and vent (DWV) systems. Manufactured to meet ASTM C1460 and CSA B602 standards, this coupling is designed to connect piping systems made from dissimilar materials such as cast iron, PVC, copper, and steel.

This coupling features a flexible elastomeric sleeve encapsulated by a 300-series stainless steel shield and clamps. The shear band provides additional rigidity at the joint, controlling deflection and reducing shear movement under load. This makes the ProFlex coupling suitable for both above-ground and underground installations where joint stability is essential.

Technical Specifications

• Model: 3001-215
• Pipe Compatibility: 2" x 1-1/2" nominal sizes (Cast Iron, PVC, ABS, Steel, Copper)
• Material – Sleeve: Neoprene or PVC elastomer (ASTM C564 compliant)
• Material – Shield and Clamps: Type 301 Stainless Steel (0.015" thickness shield)
• Connection Type: Band-sealed mechanical coupling
• Conforms to: ASTM C1460, CSA B602, UPC Listed
• Torque Spec: 60 in-lbs (torque on clamps)

Key Features

• ✅ Shielded Design: Integrated shear band minimizes pipe deflection and provides added structural support for buried or suspended lines.
• ✅ Transition Compatibility: Joins different piping materials without the need for solvent welding or threading.
• ✅ Flexible Installation: Accommodates pipe misalignment and minor movement caused by expansion, contraction, or settlement.
• ✅ Corrosion Resistance: Stainless steel components resist deterioration in high-moisture environments.
• ✅ Code-Approved: Certified for use in DWV systems by model plumbing codes in the U.S. and Canada.

Typical Applications

The Fernco 3001-215 is frequently used in remodels and retrofits where replacement or repair of DWV components requires transitioning from old piping (e.g., cast iron) to modern materials like PVC or ABS. It is suitable for both horizontal and vertical installations in residential, commercial, and institutional drainage systems.

Installation Guidance

Ensure both pipe ends are clean and square-cut. Center the coupling over the joint, align piping, and tighten stainless steel clamps using a torque wrench to the specified 60 in-lbs. No adhesives or primers are required. Always verify installation compliance with local plumbing code and engineering specifications.

Conclusion

The Fernco 3001-215 ProFlex Shielded Coupling provides a durable, code-compliant solution for joining dissimilar 2" to 1-1/2" pipe sizes in DWV and sewer systems. With its reinforced stainless steel shield, flexible sleeve, and universal compatibility, this coupling ensures structural integrity, ease of installation, and long-term reliability across a range of professional-grade plumbing applications.
