Description
A 25mm Tee Fitting is an essential plumbing component for hydroponic irrigation systems that we have been supplying to UK growers since 2017. The tee fitting allows a single 25mm feed line to be split into two separate runs, enabling you to extend your irrigation network, supply two zones from a single pump outlet, or create a loop-feed system for more even pressure distribution across a large growing area. Built for compatibility with standard 25mm polypropylene irrigation pipe, this fitting delivers a reliable, watertight connection with no specialist tools required.
Where 25mm Tee Fittings Are Used in Hydroponic Systems
In any irrigation setup that uses 25mm main line — including IWS drip systems, flood and drain layouts, NFT channels and custom recirculating setups — the tee fitting is a fundamental component for distributing flow to multiple zones or benches. The 25mm bore handles substantial flow rates from submersible pumps up to 2,000+ litres per hour, making this tee suitable for large-scale commercial installations as well as hobbyist setups. Because the fitting creates a flow split rather than a restriction, nutrient solution reaches downstream drip stakes or emitters without significant pressure drop when the system is correctly sized. We stock a full range of compatible 25mm fittings including elbows, couplers, end caps and reducers to complete your irrigation build.
Installation and Compatibility
This tee uses a push-fit or compression mechanism compatible with standard 25mm OD polypropylene irrigation pipe. Ensure the pipe is cut cleanly and squarely before inserting for a secure, leak-free connection. No adhesive or solvent welding is required. For systems requiring balanced flow across multiple branches, pair with a flow-balancing manifold or adjust branch lengths to equalise pressure. Compatible with all standard 25mm irrigation pipe and pump fittings. Combine with 25mm elbow fittings, 13mm dripper stakes and a quality submersible pump to build a reliable, scalable grow room irrigation system.
