These PVC double nipple fittings are designed for plumbers, irrigation installers, and DIY homeowners who need a compact male-to-male threaded connector that holds pressure without corrosion or cracking over time.\u003c\/p\u003e\n\u003cp\u003eEach fitting is moulded from rigid PVC (polyvinyl chloride) with NPT-compatible male threads on both ends. Available in six pipe sizes — 1\/2\" (DN15), 3\/4\" (DN20), 1\" (DN25), 1-1\/4\" (DN32), 1-1\/2\" (DN40), and 2\" (DN50) — and three colour options: White, Blue, and Grey. Body length is typically 40–80 mm depending on size; thread engagement depth follows standard NPT taper specifications.\u003c\/p\u003e\n\u003cp\u003eTypical applications include residential cold-water supply lines, drip irrigation manifolds, swimming pool and spa plumbing, and low-pressure compressed-air distribution where a lightweight, corrosion-free nipple is preferred over metal alternatives. The colour coding (White \/ Blue \/ Grey) also supports colour-coded system identification in multi-line installations.\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 NPT-threaded PVC fittings, valves, and pipe couplings.

Hand-tighten first, then add 1–2 turns with a strap wrench — avoid over-tightening, which can crack PVC fittings.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the White, Blue, and Grey colour options?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eAll three colours are made from the same rigid PVC material and carry the same pressure and temperature ratings.
