4 inch Flexible Banded Pipe Coupling Concrete x PVC

4 inch Flexible Banded Coupling for Concrete to PVC Transitions

The 4 inch flexible banded coupling is designed for joining dissimilar materials—specifically concrete to PVC pipe—in gravity-flow drainage and sewer applications. Its construction allows for secure sealing while accommodating minor movement or misalignment between pipe ends.

This coupling consists of an elastomeric sleeve with an integrated stainless steel shear ring and tightening clamps, ensuring joint stability under soil loads. The stainless steel bands maintain uniform compression, supporting consistent sealing performance across a range of installation conditions.

Performance Features

• ✅ Material Compatibility – Designed for joining 4 inch nominal concrete to 4 inch nominal PVC pipes
• ✅ Flexible Elastomer Sleeve – Provides a watertight seal while accommodating limited expansion, contraction, or angular deflection
• ✅ Stainless Steel Banded Construction – Includes clamp bands and shear ring to provide additional rigidity and soil load resistance
• ✅ Non-Pressure Systems – Suitable for non-pressurized DWV (drain, waste, and vent) and stormwater systems
• ✅ Code Compliance – Manufactured to meet ASTM C1173 and CSA B602 performance standards

Technical Specifications

• Nominal Size: 4 inches
• Application: Concrete-to-PVC pipe connections in sewer and drainage installations
• Material: Neoprene or PVC elastomer sleeve with 300-series stainless steel banding
• Standards: ASTM C1173, CSA B602, UPC/IAPMO Listed

Installation Notes

Installation requires alignment of pipe ends and torqueing of the stainless steel bands to the manufacturer's specified value—typically 60 in-lbs. A torque wrench is recommended to ensure consistent compression. Installation is suitable for use in both vertical and horizontal orientations, provided surface preparation is adequate and ends are cut square.

Common Use Cases

Used extensively in residential and commercial sewer systems for transitioning between existing concrete laterals and PVC mainline or branch piping. Also applicable in utility and stormwater systems where rigid and flexible materials intersect.

Code Reminder

Local plumbing codes may require shear-band couplings for transitions between dissimilar pipe materials to mitigate differential movement and soil pressure. Always confirm product selection against jurisdictional requirements prior to installation.

This 4 inch flexible banded coupling provides a reliable and code-compliant solution for joining concrete and PVC piping in non-pressure drainage systems. Engineered for ease of use and long-term joint integrity in demanding underground conditions. ????️
