Whether you are a DIY enthusiast tackling a garden irrigation system or a workshop builder assembling a fluid-transfer line, you need fittings that seal tight, resist corrosion, and connect pipes of different diameters without adapters piling up. These PVC T-piece 90° threaded fittings are designed to solve exactly that problem.\u003c\/p\u003e\n    \u003cp\u003eEach fitting is manufactured from rigid PVC-U (unplasticized polyvinyl chloride), a material known for its chemical resistance, dimensional stability, and long service life in both pressure and non-pressure pipe systems. The grey colour is standard for pressure-rated PVC pipework. Available in equal tee configurations (20mm, 25mm, 32mm) and reducer tee configurations (25mm×½\", 32mm×½\", 32mm×¾\"), the fittings cover pipe sizes ranging from approximately 20mm (¾\") up to 32mm (1\"), with threaded female BSP ports for secure, wrench-tightened connections.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include garden drip-irrigation manifolds where a reducer tee splits a 32mm main line down to a ½\" branch, residential grey-water plumbing where equal tees distribute flow evenly, and workshop compressed-air or chemical-dosing lines that require a corrosion-resistant, solvent-weld-compatible fitting. Long-tail applications such as \"PVC threaded reducer tee for irrigation\", \"grey PVC-U 90 degree T fitting 25mm\", and \"BSP female tee coupling for pipe manifold\" are all served by this range.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard PVC-U pressure pipe — 20mm, 25mm, and 32mm OD.
