These PVC 45° elbow solvent weld couplings deliver a precise 45-degree change of direction across a full range of pipe sizes, making them a go-to component for residential and commercial installations alike.\u003c\/p\u003e\n\u003cp\u003eEach coupling is manufactured from rigid uPVC (unplasticised polyvinyl chloride) and is designed for solvent cement bonding, creating a permanent, watertight joint. Available in inner diameters from 20mm (~¾\") to 160mm (~6¼\"), and in five colour options — White, Blue, Grey, Dark Grey, and Clear — to suit both functional and colour-coded pipework requirements. Wall thickness and body dimensions scale proportionally with pipe size.\u003c\/p\u003e\n\u003cp\u003eTypical applications include domestic cold-water supply lines, underground drainage and stormwater runs, garden irrigation networks, and industrial process pipework where a 45° offset is required. The solvent weld joint method is widely used in PVC plumbing for 45 degree elbow fittings, making these couplings compatible with standard Schedule 40 and metric-equivalent pipe systems.\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 solvent cement bonding with standard uPVC \/ PVC-U pipe.
