1-1/2 inch x 1-1/2 or 1-1/4" inch Flexible Banded Pipe Reducing Coupling Connects all Tubular Tube

TC-150 Flexible Coupling – 1-1/4" x 1-1/2" or 1-1/4" Transitions for DWV Applications

This TC-150 flexible coupling is designed to connect dissimilar DWV pipe materials and sizes with reliable sealing integrity. Featuring elastomeric construction and stainless steel clamps, this coupling supports connections between 1-1/4" and 1-1/2" nominal pipe sizes across cast iron, plastic (PVC/ABS), copper, or steel piping systems.

Ideal for gravity-flow applications, the coupling is tested to conform with applicable ASTM and CSA standards, delivering performance in non-pressurized systems such as drain, waste, and vent piping. The flexible elastomer body accommodates slight misalignment and pipe movement, reducing joint stress and improving installation versatility.

Application-Specific Benefits

• ✅ Elastomeric Flexibility – Neoprene or PVC material allows for vibration absorption and thermal expansion without compromising joint integrity.
• ✅ Stainless Steel Clamps – Dual 300-series stainless bands provide secure mechanical fastening, ensuring a uniform seal under variable load conditions.
• ✅ Multi-Material Compatibility – Engineered to join cast iron, PVC, ABS, steel, and copper pipe within the nominal sizing range.
• ✅ Removable and Reusable – Allows for future disassembly and reinstallation in maintenance and retrofit applications.
• ✅ Tool-Free Adjustment – Compatible with torque screwdriver or nut driver for precision tightening to manufacturer torque specifications.

Specifications

• Model: TC-150
• Pipe Size Compatibility: 1-1/4" to 1-1/2" nominal
• Material: Elastomeric sleeve with 300-series stainless steel clamps
• Temperature Range: Up to 140°F (intermittent peaks to 180°F)

Installation Guidelines

Install using a calibrated torque wrench or screwdriver to achieve uniform band compression. Follow torque recommendations (typically 60 in-lbs) to ensure watertight performance. For buried applications, verify the use of shear band–reinforced models as required by code.

Common Applications

Used in non-pressurized DWV systems, including:

• Residential and commercial sanitary drains
• Basement retrofits and fixture relocations
• Transitions between dissimilar pipe materials
• Repair and maintenance access points

Field Note

Flexible couplings like the TC-150 are frequently utilized during code-compliant retrofits where rigid pipe alignment is not achievable or when transitioning between pipe types without solvent welding or threading.

For installations requiring mechanical flexibility and sealing reliability between differing materials and nominal sizes, the TC-150 flexible coupling delivers field-proven performance aligned with code expectations.
