Brett Martin 110mm x 50mm Soil Pipe Level Invert Reducer / Rubber Boss Adaptor

Key Features:

• Tool-Free Installation: Push-fit rubber seal ring allows fast, secure fitting directly into a 110mm soil socket or boss.

• Leak-Proof Performance: Durable captive rubber seal compensates for thermal expansion and movement while maintaining a tight joint.

• High Chemical Resistance: Built from heavy-duty uPVC suited for domestic and light commercial soil and waste systems.

• Product Code: BS442

   

Plumbing Tip: Use silicone pipe lubricant on the male end of the 50mm waste pipe to ensure a smooth insertion through the rubber seal ring without dislodging or tearing the gasket.

Connect standard 50mm push-fit waste pipework straight into a 110mm soil stack or fitting with the BS442 110mm x 50mm Push-Fit Reducer. Designed for plumbing efficiency, this durable fitting ensures a watertight, pressure-resistant seal without requiring solvent cement or specialized tools.

Manufactured from high-grade PVC-U, this adaptor resists corrosion, hot water runoff, and common household chemicals. It is an essential component for connecting heavy discharge waste pipes—such as commercial sink or washing machine outlets—directly into soil stacks or underground drainage systems.
