[Size]: 50mm x 32mm Plug by Plug [Good Material]: PVC fittings are resilient, with high tensile and impact strength. [Easy to Install]: PVC is lightweight and easy to install. It does not require special cutting tools and is joined using solvent cement. [Application]: Gray fittings are used in drainage, waste, and vent (DWV) systems, as well as sewer and storm drainage applications. [Tips]: Suitable for systems where temperatures do not exceed 140°F. Not designed for use under pressure. UV-resistant PVC fittings contain additives that help protect against degradation from sunlight and other ultraviolet sources. Without this protection, PVC may discolor, become brittle, and crack. Impact-resistant PVC fittings are designed to withstand drops and impacts from significant heights without cracking or breaking, unlike standard plumbing-grade PVC. 100% Compatible: Structural grade PVC pipe and fittings are dimensionally compatible with standard PVC fittings. They are resilient, highly tensile, and resistant to shocks. Installation requires the use of primer and solvent cement.
