3 inch x 2 inch Flexible Banded Pipe Reducing Coupling Connects Cast Iron PVC Copper Steel or Lead Pipe

Fernco 3" x 2" Flexible Banded Coupling – For Transitioning Between Pipe Materials

The Fernco 3" x 2" Flexible Banded Coupling is a code-compliant transition fitting used to join pipes of dissimilar materials or sizes. Designed with a flexible elastomeric sleeve and stainless steel shear bands, this coupling accommodates dimensional variations and provides mechanical stability for drain, waste, and vent (DWV) systems.

It is engineered to join cast iron, PVC, steel, copper, and other types of piping within non-pressurized systems. The banded design adds rigidity to the joint, reducing the risk of shear failure and misalignment under load-bearing conditions, making it suitable for use below-grade or in structural penetrations where extra reinforcement is required.

Product Features

• ✅ Multi-Material Compatibility — Connects pipes of varying materials and diameters (3" x 2") in DWV applications.
• ✅ Stainless Steel Bands — Includes mechanical clamps and shear rings to meet structural code requirements and provide joint integrity.
• ✅ Elastomeric Flexibility — EPDM or PVC rubber body absorbs pipe movement and mitigates alignment discrepancies.
• ✅ Tool-Free Adjustability — Tightened with a torque wrench or nut driver; does not require solvent welding, threading, or flame.
• ✅ Code-Approved — Conforms to ASTM C1173, CSA B602, and UPC/IAPMO listing for use in sanitary systems.

Technical Specifications

• Size: 3" x 2" nominal pipe diameter transition
• Material: Flexible PVC sleeve with Type 300 stainless steel bands
• Connection Type: Banded mechanical clamp, no internal stops
• Certifications: ASTM C1173, CSA B602, UPC Listed

Typical Applications

Used for joining pipe of different sizes and/or materials in non-pressurized systems such as sanitary drainage, vent piping, and stormwater systems. Suitable for both above-ground and underground applications including slab penetrations, basement tie-ins, and wall cavities where structural movement must be accommodated.

Installation Considerations

Install using a torque wrench calibrated to 60 in-lbs unless otherwise specified. Ensure mating pipe ends are clean and cut square. Do not use in pressurized systems unless specifically approved by local code authority.

The Fernco 3" x 2" Flexible Banded Coupling offers a durable, code-compliant solution for transitioning between piping materials in DWV systems. Its banded design enhances mechanical stability while allowing for field-adjustable alignment and secure sealing without the need for specialty tools or adhesives.
