Hobbyists, aquaculture operators, and irrigation installers who need a reliable, chemical-resistant connection turn to metric PVC solvent weld fittings — components engineered to bond permanently and hold pressure without clamps or thread tape.\u003c\/p\u003e\n    \u003cp\u003eThese PVC metric plumbing fittings are manufactured from rigid uPVC (unplasticized polyvinyl chloride), offering a smooth bore interior and uniform wall thickness across the range. Available in seven metric sizes from 20mm (approx. ½\") up to 75mm (approx. 2½\"), and in three colour options — White, Blue, and Grey — each piece is designed for solvent cement bonding to standard metric PVC pipe. Individual pieces are sold per unit (1 pc per listing).\u003c\/p\u003e\n    \u003cp\u003eTypical applications include closed-loop aquarium filtration plumbing, koi pond and water feature pipework, rainwater harvesting manifolds, and low-pressure irrigation distribution lines. Long-tail use cases such as \"metric PVC fittings for fish tank sump build\" and \"solvent weld pipe connectors for garden pond pump\" are well served by this range.\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 metric uPVC pipe to DIN\/ISO standards.
