5 inch Flexible Banded Coupling Clay x Cast Iron PVC or Steel Pipe

5 inch Flexible Banded Coupling – Engineered for Multi-Material Transitions

The 5 inch Flexible Banded Coupling is a mechanical fitting designed to join piping systems composed of different materials such as clay, cast iron, PVC, and steel. It is commonly used in gravity-flow drainage, waste, and vent (DWV) systems where rigid couplings may be impractical due to alignment variability or material differences.

This coupling features a flexible elastomeric sleeve reinforced with stainless steel bands to ensure axial stability and compression sealing. It accommodates slight pipe misalignment and thermal expansion while maintaining a leak-resistant joint. The design meets the performance criteria required by ASTM C1173 and CSA B602 standards.

Performance Features

• ✅ Elastomeric Flexibility Allows movement and compensates for pipe alignment variances.
• ✅ Stainless Steel Band Reinforcement Provides structural integrity and uniform clamping force.
• ✅ Multi-Material Compatibility Rated for use with clay, cast iron, PVC, and steel pipe systems.
• ✅ Leak-Resistant Seal Suitable for above- or below-grade DWV connections.
• ✅ Field-Serviceable Easily removed and reinstalled for inspection or component replacement.

Technical Specifications

• Size: 5 inches nominal pipe diameter
• Material: Neoprene or similar elastomer (sleeve), 300-series stainless steel (bands)
• Connection Type: Mechanical clamp with banded compression seal
• Standards: ASTM C1173, CSA B602
• Application: Drainage, waste, and vent (DWV) piping systems

Installation Guidance

To install, align the pipe ends and position the coupling centrally over the joint. Use a torque wrench to tighten the stainless steel bands to the manufacturer’s specified torque (typically 60 in-lbs). Clean pipe surfaces prior to installation for optimal sealing. Coupling installation should comply with local plumbing code requirements.

Typical Applications

Flexible banded couplings are used in both new construction and repair work. Common installation points include transitions between dissimilar pipe materials, replacement of damaged pipe sections, and connections in non-pressurized soil and waste systems. They are suitable for underground or above-ground use within the scope of DWV applications.

Material Considerations

Using elastomeric flexible couplings with stainless steel reinforcement helps isolate vibration, accommodate minor movement, and extend the service life of piping systems. These characteristics are particularly beneficial when joining rigid materials subject to differential settlement or thermal expansion.

The 5 inch Flexible Banded Coupling is a code-compliant, field-tested solution for DWV system connections requiring material flexibility and mechanical sealing integrity.
