[Size]: 50mm x 40mm Plug by Plug[Good Material]: PVC fittings are resilient, high tensile and impact strength.[Easy to install]: PVC is lightweight, easy to install, does not require special cutting tools and is installed by solvent cementing.[Application]: Gray fittings used for drain, waste and vent (DWV), sewer and storm drain applications.[Tips]: For use where systems will not exceed 140 F. Not intended for use under pressure.Description:UV ResistantPVC fittings contain a healthy additive that inhibits the impact of sunlight and other ultraviolet sources on the molecular structure of PVC. Without it, the PVC would yellow, crack, become brittle and break. Impact Resistance PVC fittings can take a beating. They are designed to withstand knocks or drops from a significant height and will not suffer cracks or breakage compared to standard quality PVC fittings. plumbing.100% CompatibleStructural grade PVC pipe and fittings are dimensionally compatible with quality PVC fittings.Easy to installThey are resilient, highly tensile and impact resistant. Installation requires the use of primer and solvent cement.TipsPVC pressure fittings are for use in pressure systems with temperatures not to exceed 140F.Specifications:Product Name: Reducing CouplingMaterial: PVCColor: GreySize: 50mm x 40mm / 1.97 x 1.57 (hub x hub)Overall size (approx.): 57mm x 67mm / 2.24 x 2.64(D*H)Weight : 96gPackage content : 2pcs x Reducing coupling,
