Wavin 2S299B OsmaS PVCU Boss Adaptor Black 50×40 Solvent Weld

The Wavin 2S299B OsmaS PVCU Boss Adaptor is a straight, single-piece fitting with two plastic welded (solvent weld) ends. It has a DN 50 connection on one side and a DN 40 connection on the other, allowing a 50 mm pipe to be reduced to 40 mm within a PVC-U system.

This black PVC-U adaptor is designed for the Wavin OsmaS range of soil and waste pipework. It suits domestic and light commercial installers working on new builds or replacement work where a reduction between these two sizes is required. OsmaS is Wavin’s above-ground system, so this fitting is intended for above-ground use rather than below-ground drainage.

Made from polyvinyl chloride (PVC-U) and untreated on its surfaces, it is a lightweight, durable fitting with a technical lifespan stated as 100 years.
