[Size]: 50mm x 32mm Hub by Hub [Good Material]: PVC fittings are resilient with high tensile and impact strength. [Easy to Install]: Lightweight and easy to handle, PVC fittings do not require special cutting tools and are installed using solvent cement. [Application]: Gray fittings are suitable for drainage, waste, and vent (DWV) systems, sewer, and storm drainage applications. [Tips]: For use in systems where temperatures do not exceed 140°F. Not designed for pressurized systems. UV-resistant PVC fittings contain additives that protect against sunlight and ultraviolet radiation, helping prevent discoloration, cracking, and brittleness. Impact-resistant design allows the fittings to withstand drops or impacts without cracking or breaking, compared to standard plumbing-grade PVC. 100% Compatible: Structural grade PVC pipe and fittings are dimensionally compatible with standard PVC fittings. Resilient, highly tensile, and resistant to shocks. Installation requires the use of primer and solvent cement.
