When a leaking joint or a missing connector brings your plumbing project to a halt, you need fittings that go on fast and hold tight. Whether you are a homeowner tackling a garden irrigation upgrade, a maker building a custom water distribution system, or a small workshop running coolant lines, these UPVC grey pipe fittings give you the right shape for every junction without hunting across multiple suppliers.
This listing covers a comprehensive range of UPVC (unplasticized PVC) solvent-weld fittings in grey, spanning inner diameters from 20 mm (approx. 3/4 in) up to 110 mm (approx. 4-3/8 in). The lineup includes Straight couplings, 90° Elbows, 45° Elbows, Tees, Caps, Reducing Straights, Female and Male Threaded Straights, Female-to-Female Straights, Female 90° Elbows, Female-to-Female 90° Elbows, Reducing Tees, Female Tees, Ball Valves, Double Union Ball Valves, Check Valves, Union Joints, Union Caps, Flanges, and Reducing Ring Sockets — all in a single product listing.
Typical use cases include residential cold-water supply lines and drain runs, garden drip-irrigation and sprinkler manifolds, aquaponics and pond filtration plumbing, and light-duty industrial process piping where a solvent-weld UPVC pipe fitting system is specified.

Match the fitting inner diameter (ID) to the outer diameter (OD) of your pipe. For example, a 20 mm fitting accepts a 20 mm OD UPVC pipe. For reducing fittings (e.g., 32*20 mm), the larger number is the main-run pipe OD and the smaller number is the branch or reduced-end OD. If you are unsure, measure your existing pipe OD with calipers and select the matching size from the variant dropdown.
No. UPVC is rated for cold-water service only — typically up to around 60 °C (140 °F) under low pressure. For hot-water supply lines, underfloor heating, or steam applications, you would need CPVC, PP-R, or copper fittings instead. These grey UPVC fittings are ideal for cold mains, irrigation, drainage, and similar ambient-temperature systems.
Yes. UPVC does not rust, corrode, or scale the way metal fittings do, and it resists most household acids, alkalis, and fertilizer solutions commonly found in irrigation systems. It is not resistant to strong solvents, concentrated oxidising acids, or aromatic hydrocarbons, so avoid contact with those substances.
Use a dedicated UPVC / PVC solvent-weld cement (also called PVC primer and cement, or one-step PVC cement). Apply a thin, even coat to both the pipe end and the fitting socket, push together with a slight twist, and hold for 30 seconds. Allow the joint to cure for at least 15 minutes before handling and 24 hours before pressurising. Do not use general-purpose adhesives or silicone sealant as a substitute.
Yes. The Female Straight, Male Straight, Female 90° Elbow, Female Tee, and similar threaded shapes use BSP (British Standard Pipe) threads, which are the standard for plumbing fittings in most markets outside North America. The size label (e.g., 20 mm : 1/2") shows the pipe OD alongside the BSP thread equivalent. Use PTFE tape on male threads for a leak-free seal.
Choose a Union Joint or Union Cap when you need to be able to disassemble the pipeline in the future — for example, to service a pump, filter, or UV steriliser — without cutting the pipe. A Double Union Ball Valve combines shut-off control with union ends on both sides, making it the go-to choice for equipment isolation points in aquaponics, pond, and pool filtration systems where regular maintenance is expected.
Generally yes, as long as the pipe OD and fitting ID match and both follow the same dimensional standard. UPVC fittings are widely standardised, so a 32 mm fitting from this listing will accept any 32 mm OD UPVC pipe regardless of brand. For threaded connections, confirm the thread standard (BSP vs NPT) before mixing brands, as BSP and NPT threads are not interchangeable.
