These UPVC cap end caps are engineered for DIY builders, plumbers, and renovation contractors who demand a clean, permanent seal on dark grey PVC drainage systems — from bathroom waste lines to garden drainage channels.\u003c\/p\u003e\n\u003cp\u003eEach cap is moulded from unplasticised PVC (UPVC) in a dark grey finish that blends seamlessly with standard drainage pipework. The socket end accepts solvent-weld adhesive for a watertight, rigid bond. Available in nine pipe diameters spanning ø20 mm (approx. ¾ in) through ø110 mm (approx. 4⅓ in), with wall thickness and socket depth scaled proportionally to each size.\u003c\/p\u003e\n\u003cp\u003eTypical applications include blanking off unused branch outlets on soil stacks, capping inspection chamber ports during construction, sealing the dead end of underground drainage runs, and pressure-testing completed pipework before backfilling. Long-tail use cases: UPVC drain pipe end cap ø110mm, dark grey PVC blanking plug for 50mm waste pipe, solvent-weld cap for 32mm basin waste.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for standard UPVC \/ PVC-U drainage pipe systems.

UPVC is widely used for below-ground drainage because it resists soil moisture, mild acids from groundwater, and root intrusion. Once solvent-welded, the joint is rigid and watertight. Ensure the pipe trench is properly bedded and backfilled to avoid point loading on the fitting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use these caps to pressure-test a drainage system?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes — temporarily capping pipe ends with solvent-welded UPVC caps is a common method for air or water pressure testing drainage runs before covering. Allow the solvent weld to cure fully (typically 24 hours at room temperature) before applying test pressure.
