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

6" Flexible Banded Coupling – Built for Transitioning Dissimilar DWV Pipe Materials

The 6" flexible banded coupling is designed for joining pipes of the same or different materials in non-pressure drainage, waste, and vent systems. Featuring an elastomeric sleeve with a 300-series stainless steel shield and clamps, it maintains structural integrity under soil loads while providing a leak-resistant seal between cast iron, PVC, ABS, copper, and steel piping.

Key Performance Features

• ✅ Shielded Support – Integral stainless steel band helps prevent pipe misalignment and resists shear force during backfill or thermal cycling
• ✅ Code-Compliant Material – Flexible neoprene sleeve meets ASTM C1173 and CSA B602 specifications for DWV connections
• ✅ Corrosion-Resistant Hardware – Stainless steel clamps offer uniform compression with excellent resistance to chemical and environmental degradation
• ✅ Pipe Compatibility – Connects 6" nominal cast iron, plastic (PVC or ABS), copper, or steel piping without the need for adhesives or fusion
• ✅ Movement Accommodation – Flexibility helps absorb vibrations and minor settling or expansion, maintaining joint integrity

Technical Specifications

• Nominal Size: 6" x 6"
• Sleeve Material: Neoprene or PVC (depending on model), suitable for above- and below-grade use
• Shield & Clamp: 300-series stainless steel
• Standards: ASTM C1173, CSA B602, UPC listed for DWV systems
• Temperature Range: Up to 140°F continuous; intermittent up to 180°F

Application Use

Intended for gravity-flow DWV applications, this coupling is frequently used during system repairs, retrofits, or transitions between old and modern piping materials. It is suitable for underground or exposed runs, and ideal for connections where movement or misalignment is a concern.

Installation Guidance

Installation requires only standard tools. Align pipes squarely, center the coupling over the joint, and torque each clamp to manufacturer specifications (typically 60 in-lbs). No solvent welding, soldering, or fusion bonding required.

Professional Insight

For contractors working on older buildings or mixed-material piping systems, banded couplings provide a fast, compliant solution for reliable connections that tolerate expansion, shifting, or vibration. Their uniform sealing pressure and adaptability to a range of substrates make them essential components in field retrofits.

Choose the 6" flexible banded coupling for a secure, standards-compliant connection where durability and alignment retention are critical. Trusted by industry professionals for decades, these fittings deliver long-term performance in demanding DWV system configurations.
