Grey PVC Water Supply Pipe Fittings — Reliable Connections for Every Plumbing Layout
When a plumbing run demands a direction change, a branch split, or a clean termination, using the wrong fitting type creates leaks, pressure drops, and costly rework. These grey PVC water supply pipe fittings are engineered for cold-water pressure systems where dimensional accuracy and solvent-weld integrity matter — making them the go-to choice for plumbers, irrigation contractors, and serious DIY builders who need fittings that perform without compromise.
This listing covers 18 distinct fitting types — including Plain End Cap, 90° Elbow, 45° Elbow, Socket, Equal Tee, Reducing Tee, Equal Cross, Reducing Socket, 45° 3-Way Y Connector, 3-Way / 4-Way / 5-Way / 6-Way Elbow, BSP Male and Female Thread Straight Connectors, BSP Male Thread × Hose Barb, Plain Socket Ball Valve, and BSP Female Thread Ball Valve. Sizes span 20mm (approx. ¾ in) through 90mm (approx. 3½ in), with BSP threaded variants sized in standard imperial fractions (½" to 2½"). All fittings are manufactured from grey uPVC compound formulated for water supply service.
Typical applications include domestic cold-water distribution lines, garden and agricultural irrigation manifolds, rainwater harvesting pipework, and light-duty industrial water transfer systems. Whether you are branching a 63mm main with a reducing tee, capping a 20mm stub-out with a plain end cap, or isolating a circuit with a plain socket ball valve, these grey PVC water supply pipe fittings cover the full range of connection geometries in a single product family.

18 Fitting Types in One Family
From plain end caps and equal tees to 6-way elbows and ball valves, every geometry needed to design a complete water supply network is available in matching grey uPVC — eliminating material mix-and-match issues.
📏
Wide Size Range: 20mm – 90mm
Metric socket sizes cover 20, 25, 32, 40, 50, 63, 75, and 90mm. Reducing types span common step-down combinations (e.g., 63×20mm, 75×50mm). BSP threaded variants cover ½" through 2½" for transition to threaded systems.
💧
uPVC Compound for Water Supply Service
Formulated from unplasticised PVC (uPVC) with UV stabilisers and impact modifiers. The material is non-reactive with potable cold water, resists scale build-up, and maintains dimensional stability across typical ambient temperature ranges (typically 0–45 °C).
🔩
Solvent-Weld and BSP Thread Options
Plain socket types use standard solvent-cement jointing for a permanent, leak-free bond. BSP male and female thread connectors and ball valves allow integration with existing threaded metalwork, pumps, and filter housings without adapters.
⚖️
Consistent Wall Thickness and Socket Depth
Socket depth and spigot clearance are held to metric DIN/ISO tolerances, ensuring full solvent-cement contact area and rated working pressure retention. Reducing sockets and tees maintain concentric bore alignment to minimise turbulence at transitions.
🛠️
Covers Complex Junction Geometries
Multi-port elbows (3-way, 4-way, 5-way, 6-way) and the 45° Y connector allow manifold-style branching without custom fabrication — particularly useful for irrigation headers, rainwater distribution, and multi-zone plumbing layouts.
