PVC Water Pipe Fittings 20mm-75mm Ball Valve Socket Solvent Weld-Female Thread

Match the size to your pipe's outer diameter (OD). Standard metric PVC pressure pipe is labelled by OD: 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, or 75 mm. If you are unsure, measure the outside of the pipe with calipers — do not measure the bore. For Solvent Weld variants the socket should slide snugly over the pipe end before cement is applied.

Solvent Weld sockets are bonded permanently to plain-end PVC pipe using PVC solvent cement, creating a joint that is as strong as the pipe itself. Female Thread (BSP) sockets accept a male BSP-threaded fitting and can be unscrewed for maintenance or replacement without cutting the pipe. Choose Solvent Weld for new permanent runs and Female Thread where future access is needed.

No. These PVC ball valve sockets are rated for cold-water service only. Rigid PVC begins to soften at elevated temperatures and is not suitable for hot-water supply lines, heating circuits, or any steam application. For hot-water service, use CPVC or brass fittings rated for the required temperature.

Yes. PVC does not corrode, rust, or react with soil moisture or chlorinated water, making it well-suited for garden irrigation, outdoor water supply, and buried runs. For above-ground outdoor installations exposed to direct sunlight over long periods, consider wrapping or painting the valve to limit UV degradation, as standard PVC can become brittle with prolonged UV exposure.

The colour is a visual identifier only — all three colours share the same PVC material and pressure rating. Many installers use colour-coding to distinguish zones: for example, White for cold supply, Blue for irrigation, and Gray for drainage or secondary circuits. Choose the colour that matches your existing pipework or your own colour-coding convention.

For Solvent Weld variants you need PVC solvent cement and a brush or dauber (not included), plus a pipe cutter or hacksaw to prepare square pipe ends. No heat gun or press tool is required. For Female Thread variants you need PTFE thread-seal tape and an adjustable spanner to tighten the mating male fitting. The ball valve lever itself requires no tools to operate after installation.

The lever handle indicates flow direction: when the lever is parallel to the pipe, the valve is fully open; when the lever is perpendicular (at 90°) to the pipe, the valve is fully closed. This makes it easy to confirm the valve position at a glance without any additional indicators.
