Whether you are a plumber finishing a domestic water supply line, a landscaper capping off an irrigation branch, or a DIYer sealing a drainage stub, these PVC UPVC plain end caps give you a secure, tool-free push-fit closure that holds firm under normal working pressure.\u003c\/p\u003e\n\u003cp\u003eEach cap is moulded from rigid UPVC (unplasticised polyvinyl chloride) with a thick wall construction for added strength. The plain socket bore accepts standard OD pipe in sizes from 20 mm (approx. 0.79 in) up to 110 mm (approx. 4.33 in), covering the most common residential and light-commercial pipe diameters. Wall thickness and exact bore tolerance vary by size — see variant options for specifics.\u003c\/p\u003e\n\u003cp\u003eTypical applications include capping unused tee or cross outlets on cold water supply manifolds, terminating irrigation sub-mains during staged installation, sealing drainage inspection stubs, and blanking off redundant pipe ends during pressure testing of new plumbing systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e Compatible with standard OD UPVC pressure pipe to BS EN 1452 \/ AS\/NZS 1477 and equivalent schedules.
