These gray PVC slip fittings are designed for hobbyists, aquarists, and DIY plumbers who need a clean solvent-weld connection that holds under continuous water pressure without corrosion or discoloration.\u003c\/p\u003e\n\u003cp\u003eEach fitting is molded from rigid gray PVC (polyvinyl chloride), compatible with standard metric pipe ODs. Available in five pipe sizes — 20mm (~¾ in), 25mm (~1 in), 32mm (~1¼ in), 40mm (~1½ in), and 50mm (~2 in) — with socket-style slip ends for solvent cement bonding. Wall thickness and socket depth are sized to match standard Schedule-equivalent PVC pipe for a secure, leak-free joint.\u003c\/p\u003e\n\u003cp\u003eTypical applications include closed-loop aquarium sump plumbing, koi pond filtration circuits, drip irrigation manifolds, and rainwater harvesting pipe runs. The neutral gray finish blends with most PVC pipe stock and cabinet interiors, making these fittings a go-to choice for aquarium sump return line fittings, PVC pipe coupling for water features, and DIY pond pump plumbing projects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e Compatible with standard metric PVC pressure pipe: 20mm, 25mm, 32mm, 40mm, and 50mm OD.
