PVC Pipe Tee Fitting with BSP Threaded Port — Reliable 3-Way Solvent Weld Connection
When a plumbing run needs to branch off cleanly — whether you're roughing in a bathroom, extending an irrigation line, or building a DIY fluid system — a loose or mismatched tee fitting causes leaks that are expensive to fix after the walls close. These PVC pipe tee fittings are designed for DIYers, plumbers, and irrigation installers who need a dimensionally accurate, chemically resistant 3-way junction they can trust.
Each fitting is constructed from rigid PVC (polyvinyl chloride) with a solvent-weld socket on two ports and a BSP (British Standard Pipe) threaded port on the branch. Available in six pipe sizes — 20mm (½"), 25mm (¾"), 32mm (1"), 40mm (1¼"), 50mm (1½"), and 63mm (2") — and four colour options: White, Blue, Grey, and Dark Gray. Sold in packs of 1, 2, 3, or 5 pieces to match your project scope.
Typical applications include cold-water domestic plumbing branch connections, garden drip and sprinkler irrigation manifolds, aquaculture and pond filtration pipework, and workshop compressed-air distribution lines where PVC-rated pressures apply. The BSP threaded branch accepts standard BSP male adapters, valves, and gauges, making this PVC pipe tee fitting a versatile junction point for mixed-material systems.

Compatibility: Solvent-weld sockets are compatible with standard Schedule 40 / Class D PVC pipe of the corresponding nominal size. BSP threaded branch is compatible with standard BSP male fittings, ball valves, and threaded adapters. Not suitable for hot-water systems or steam lines.
✅ Key Features of These PVC Pipe Tee Fittings
🔧
Dual-Connection Design
Two solvent-weld sockets provide a permanent, leak-free bond to plain-end PVC pipe; the BSP threaded branch allows tool-free connection to valves, gauges, or threaded adapters without additional couplings.
📐
Six Pipe Sizes Available
Covers the most common residential and light-commercial pipe diameters: 20mm (½"), 25mm (¾"), 32mm (1"), 40mm (1¼"), 50mm (1½"), and 63mm (2"). Select the size that matches your existing pipe run.
🎨
Four Colour Options
White, Blue, Grey, and Dark Gray finishes allow colour-coding of pipe systems by fluid type or pressure zone — a practical convention in multi-line installations and commercial plant rooms.
🛡️
Rigid PVC Construction
PVC resists corrosion, scale build-up, and most common household chemicals. The material maintains dimensional stability across typical cold-water temperature ranges, reducing the risk of joint creep over time.
📦
Flexible Pack Quantities
Available in 1, 2, 3, or 5-piece packs so you can order exactly what a single repair needs or stock up for a full installation run without over-purchasing.
⚙️
Standard BSP Thread Specification
The threaded branch conforms to BSP (British Standard Pipe) dimensions, ensuring interchangeability with the broad ecosystem of BSP-compatible valves, pressure gauges, and male adapters available globally.

❓ Frequently Asked Questions
Which pipe size should I choose for my existing plumbing?
Match the fitting size to your pipe's nominal outside diameter. As a guide: 20mm fits ½" nominal pipe, 25mm fits ¾", 32mm fits 1", 40mm fits 1¼", 50mm fits 1½", and 63mm fits 2" pipe. If you are unsure, measure the outside diameter of your existing pipe with calipers and compare to the nominal size chart. When in doubt, contact us with your measurement and we can confirm the correct variant.
Can I use these fittings with hot water lines?
No. These fittings are manufactured from rigid PVC, which is rated for cold-water applications only. PVC softens at elevated temperatures and is not suitable for hot-water supply lines, heating circuits, or steam applications. For hot-water systems, consider CPVC or brass fittings rated for the required temperature range.
What solvent cement should I use for the weld joints?
Use a PVC solvent cement (also called PVC glue or solvent weld adhesive) formulated for rigid PVC pipe and fittings. Apply a PVC primer first to clean and soften the mating surfaces, then apply cement to both the pipe end and the socket interior. Push together with a quarter-turn and hold for 30 seconds. Allow the joint to cure fully before pressurising — typically 15–30 minutes for handling and 24 hours for full pressure service, depending on ambient temperature and humidity.
Is the BSP threaded branch compatible with NPT fittings?
BSP and NPT (National Pipe Thread) are different thread standards and are not directly interchangeable. BSP threads have a 55° thread angle and parallel or tapered profiles (BSPP/BSPT), while NPT uses a 60° angle. Using an NPT fitting on a BSP port — or vice versa — can result in cross-threading or leaks. If your system uses NPT fittings, you will need a BSP-to-NPT adapter. Contact us if you need clarification on thread compatibility for your specific application.
Can these tee fittings be used for irrigation and garden watering systems?
Yes. PVC tee fittings are widely used in drip irrigation, sprinkler manifolds, and garden water distribution systems. The solvent-weld sockets provide a permanent, leak-free connection to PVC irrigation pipe, while the BSP threaded branch can accept drip emitters, solenoid valves, or pressure regulators with a matching BSP male thread. Ensure the operating pressure of your irrigation system stays within the pressure rating of the selected fitting size.
How do I choose between White, Blue, Grey, and Dark Gray?
Colour choice is primarily functional for system identification. White is the most common general-purpose colour for domestic plumbing. Blue is often used to designate cold-water supply lines in multi-pipe installations. Grey is a standard colour for waste and drainage PVC in many regions. Dark Gray is commonly associated with pressure-rated or industrial-grade PVC systems. Choose the colour that matches your existing pipework or your preferred colour-coding convention. All colours share the same dimensional and mechanical specifications.
What is the difference between solvent weld and push-fit connections?
Solvent weld (used on the run ports of this fitting) creates a permanent chemical bond between the fitting socket and the pipe end — the solvent partially dissolves both surfaces, which then fuse as the cement cures. This produces a joint as strong as the pipe itself and is not reversible without cutting. Push-fit connections use an internal rubber seal and grab ring to grip the pipe mechanically and can be released with a release tool. This fitting uses solvent weld for the two run ports and BSP threads for the branch port, so plan your installation accordingly before bonding.
