When a plumbing run needs to branch off cleanly without leaks or weak joints, choosing the wrong tee fitting costs time and money. DIYers, plumbers, and irrigation installers who work with rigid pipe systems need a tee connector that bonds securely, resists corrosion, and holds pressure over the long term. These grey UPVC slip 3-way tee connectors are engineered for exactly that job.
Each fitting is manufactured from unplasticized polyvinyl chloride (UPVC) in a neutral grey finish. The slip (solvent-weld) socket ends accept standard metric pipe in interior diameters ranging from 20mm (~¾ in) up to 110mm (~4⅓ in), covering the most common residential and light-commercial pipe sizes. Wall thickness and socket depth are sized to meet typical Schedule 40 / Class D equivalent standards, ensuring a full-depth bond when used with compatible solvent cement.
Typical applications include cold-water supply branch lines, garden and agricultural drip-irrigation manifolds, rainwater harvesting distribution headers, and above-ground or below-ground drainage laterals. Long-tail use cases such as "UPVC tee fitting for irrigation system", "grey PVC 3-way connector for cold water pipe", and "solvent-weld tee 50mm drainage" are all well served by this range.

Match the interior diameter (ID) of the fitting to the nominal outer diameter of your UPVC pipe. For example, if your pipe is marked DN25 or 25mm OD, select the 25mm variant. When in doubt, measure the pipe's outer diameter with calipers and compare to the size chart — the slip socket is sized to accept the pipe's OD directly.
No. UPVC is rated for cold-water service only, typically up to 60 °C (140 °F) under reduced pressure. For hot-water supply lines, use CPVC or copper fittings instead. These tees are ideal for cold-water supply, irrigation, rainwater, and drainage applications.
Yes. UPVC is chemically inert and does not corrode in soil environments, including acidic soils and areas with fertilizer runoff. Ensure the trench is free of sharp stones that could abrade the pipe, and follow local codes for burial depth and bedding material.
Use a UPVC-rated solvent cement (not ABS cement). Clean and dry both the pipe end and socket, apply a thin, even coat of cement to both surfaces, push the pipe fully into the socket 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 pressure testing.
A properly made solvent-weld joint chemically fuses the pipe and fitting into a single piece, typically achieving joint strength equal to or exceeding the pipe wall itself. This makes it more resistant to pull-out and vibration than threaded connections, which rely on mechanical engagement alone.
Yes. These UPVC tee connectors are widely used in drip-irrigation manifolds, garden water distribution headers, and agricultural supply lines. They are compatible with standard metric UPVC pipe used in most residential and light-commercial irrigation setups. Confirm your pipe's nominal diameter before ordering.
These fittings are suitable for above-ground and below-ground drainage of non-pressurized waste water (gravity drainage). For pressurized drainage or sewage systems, verify the pressure rating of the specific size variant you need and consult local plumbing codes.
