Supreme 25mm x 1″ Male Thread Tee
Maximise your system throughput with the heavy-duty Supreme 25mm x 1″ Male Thread Tee. Specifically engineered for high-volume commercial and domestic systems, this professional-grade compression junction allows you to establish a secure branch-off point from a 25mm mainline while integrating a full-bore 1″ threaded valve, heavy-duty manifold, or pump setup with zero flow restriction.
Built to Withstand Extreme Structural Stress
Large-scale watering mainlines face constant hydraulic shocks and ground shifting. This Supreme fitting is molded from premium, high-impact polypropylene copolymer that easily absorbs pressure spikes and resists intense frosts. Fully UV-stabilised and chemical-resistant, it is perfectly suited for direct burial in agricultural fields, commercial sports pitches, and extensive garden landscapes.
Why This 25mm x 1″ Supreme Tee is the Professional Choice:
- High-Flow Transition: Connects 25mm MDPE or LDPE water pipes directly to a heavy-duty 1″ Male BSP thread.
- Industrial Pressure Rating: Fully certified to handle demanding working environments up to PN16 (16 Bar / 232 PSI).
- Rapid Compression Grip: Ergonomic interlocking nuts ensure a completely secure mechanical lock using simple hand-tightening.
- Full-Bore Engineering: Optimized internal design eliminates turbulence and maintains maximum water velocity across the split.

Installation Best Practice:
To ensure a completely leak-free seal under continuous high pressure, make sure the 25mm pipe is cut clean and square. Apply a generous layer of heavy-duty PTFE thread sealing tape to the 1″ male thread before manually spinning it into your female component. Do not use metal wrenches; firm hand-tightening is all that is required.
