These UPVC end caps are perfect for finishing off the ends of 1-1/4\ PVC pipes in DIY projects. They're 2-pack, with each cap having an inner diameter of about 1.66\ (42.2mm) and outer diameter of 2.07\ (52.5mm). Height is roughly 1.79\ (45.5mm). Made from UPVC – that's unplasticized PVC – so they're corrosion-resistant, strong, and lighter than metal. The inner wall is thickened for a tight, secure fit on pipes. They give a clean, smooth finish that hides rough edges, great for furniture, shelving, garden structures, or any PVC frame you're building. Use them indoors or outdoors; they handle weather well. You'll need PVC primer and solvent cement for a permanent bond. Easy to install: just apply adhesive and press onto the pipe end. A simple but essential part for making your DIY projects look professional and finished.
