UPVC straight reducing connectors solve this precisely: they bridge two different pipe diameters in a single inline fitting, maintaining flow integrity without the need for adapters or makeshift solutions. They are the go-to choice for irrigation contractors, plumbers, and DIY builders who need a clean, durable size transition.\u003c\/p\u003e\n\u003cp\u003eThese UPVC straight reducing connectors are manufactured from unplasticized PVC (UPVC), a rigid, chemically stable thermoplastic. Each fitting features a straight-through body with two socket ends of differing diameters, designed for solvent-cement (glue) jointing. Available sizes span 25×20mm (~1\"×¾\") through 63×50mm (~2½\"×2\"), covering the most common residential and light-commercial pipe diameter combinations. Wall thickness and socket depth are sized to match standard UPVC pipe schedules.\u003c\/p\u003e\n\u003cp\u003eTypical applications include drip and sprinkler irrigation mainline-to-lateral transitions, domestic cold-water supply branch reductions, garden water feature plumbing, and greenhouse irrigation distribution networks. The rigid UPVC construction makes these fittings equally suited to buried underground runs and exposed above-ground installations where UV exposure is limited.\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 Designed for standard UPVC pressure pipe (solvent-weld socket type).
