Gray PVC-U Pipe Adhesive Fittings Sleeve Elbow Tee Cross Reducer Ball Valve Cap

Match the fitting size to the outer diameter (OD) of your PVC-U pipe. For example, a "20 mm" fitting accepts pipe with a 20 mm OD. If you are connecting to a BSP-threaded component, select the variant that lists the corresponding thread size (e.g., "25 mm × ¾ inch"). When in doubt, measure your existing pipe OD with calipers before ordering.

Use a two-step solvent-cement system: apply a PVC primer/cleaner first to both the pipe end and the fitting socket, then apply a PVC solvent cement rated for pressure pipe. Allow the joint to cure for the time specified on the cement tin (typically 15–30 minutes before handling, 24 hours before pressure testing) and ensure adequate ventilation during application.

No. PVC-U is rated for cold-water service only — typically up to 45 °C (113 °F). For hot-water lines, consider CPVC or PP-R fittings instead. Using PVC-U above its rated temperature can cause deformation and joint failure.

Yes. Gray PVC-U is widely used in garden irrigation, drip systems, and sprinkler networks. The material resists UV degradation better than clear PVC, though burying the pipe or providing shade will extend service life further. The Sleeve × Hose Nozzle and Male Thread × Hose Nozzle variants are particularly useful for connecting to standard garden hose barbs.

PVC-U does not rust or corrode in the way that metal fittings do. It is resistant to most household chemicals, chlorinated water, mild acids, and alkalis. It is not suitable for concentrated solvents, aromatic hydrocarbons, or highly oxidising chemicals. For aggressive chemical environments, consult a chemical resistance chart for PVC-U before installation.

A Reducer Sleeve is a full-length coupling that joins two pipes of different diameters end-to-end (e.g., 50 mm pipe to 32 mm pipe). A Reducing Ring is a short insert that fits inside a standard socket to reduce its bore, allowing a smaller pipe to be inserted into a larger fitting socket. Reducing Rings are useful when you want to adapt an existing fitting rather than replace it.

The Ball Valve Sleeve and Female Thread Ball Valve fittings are installed using the same solvent-weld or threaded technique as the rest of the range. Ensure the ball valve is in the open position during solvent cementing so that solvent fumes can escape and the ball seal is not damaged by heat build-up. Allow full cure time before operating the valve under pressure.

Select a Sleeve × Male Thread or 90° Elbow × Female Thread variant that matches your pipe OD and the BSP thread size of the metal component. Use PTFE tape on the male thread before assembly to ensure a watertight seal. Avoid over-tightening threaded joints into PVC-U female sockets, as this can crack the fitting.
