These PVC straight union pipe connectors are designed for DIYers, plumbers, and irrigation installers who need a dependable solvent-weld socket fitting that goes together fast and stays sealed.\u003c\/p\u003e\n\u003cp\u003eEach connector is made from rigid PVC (polyvinyl chloride), offering excellent chemical resistance and long service life in both above-ground and buried applications. The solvent weld (Klebemuffe) socket ends accept standard pipe ODs across the DN15–DN40 range — inner diameters spanning 20mm (~¾ in) to 50mm (~2 in). Available in White, Grey, and Blue to support color-coded piping systems or match existing installations.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include cold water supply lines where a straight inline coupling is needed, residential and commercial irrigation systems requiring a clean pipe-to-pipe union, and drainage or waste-water runs where a solvent-bonded straight connector ensures a permanent, watertight joint. Long-tail applications include PVC pipe repair coupling DN25, straight solvent weld fitting 32mm, and inline pipe union connector for irrigation.\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 pipe OD for DN15 (20mm), DN20 (25mm), DN25 (32mm), DN32 (40mm), and DN40 (50mm).
