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

Fernco 1056-22 Flexible Banded Coupling – For Secure Transitions Between Dissimilar Pipe Materials

The Fernco 1056-22 Flexible Banded Coupling is a high-performance plumbing component engineered for joining 2-inch nominal pipes of varying materials. Designed to meet the demands of professional-grade installations, this coupling provides a secure, watertight seal and mechanical stability where traditional rigid fittings fall short.

Constructed for code-compliant use in above- and below-grade drainage, waste, and vent (DWV) systems, the 1056-22 features a stainless steel band clamp assembly and a durable elastomeric sleeve, ensuring compatibility across cast iron, PVC, steel, copper, and lead piping systems.

Key Performance Attributes

• ✅ Multi-Material Compatibility – Transitions between dissimilar piping materials with consistent pressure sealing integrity.
• ✅ Stainless Steel Shield and Clamps – Incorporates 300-series stainless bands to maintain shape and support under load and thermal cycling.
• ✅ Neoprene Sleeve – Resilient elastomer resists microbial growth, acids, alkalis, and chemical degradation in harsh DWV environments.
• ✅ ASTM C1460 & CSA B602 Compliant – Approved for use in regulated plumbing systems and meets national and international mechanical code standards.

Installation and Use

The Fernco 1056-22 coupling is designed for straightforward installation using a torque wrench to evenly tighten stainless band clamps to recommended specifications (60 in-lbs). No primer or solvent welding is required. It accommodates slight pipe misalignment and movement due to its flexible construction, making it particularly useful in retrofit and repair applications.
