These PVC elbow pressure pipe fittings are designed for hobbyists, pond builders, and DIY plumbers who need a dependable solvent-weld connection that holds under continuous water pressure.\u003c\/p\u003e\n    \u003cp\u003eEach elbow is manufactured from rigid PVC (polyvinyl chloride), offering a lightweight yet structurally solid 90° bend. Available in nine sizes ranging from 20mm (~¾ in) to 110mm (~4⅓ in), the fittings accept standard solvent cement for a permanent, watertight bond. Wall thickness and pressure rating vary by diameter — see variant options for exact specifications.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include aquarium sump return lines, koi pond filtration loops, irrigation manifolds, and residential grey-water drainage. Whether you are routing flow around a cabinet corner in a reef tank build or connecting a pond pump to a UV clarifier, these PVC elbow fittings deliver a clean, code-friendly solution for solvent-weld 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 Fits standard metric PVC pressure pipe (Class C \/ PN12 equivalent).
