These brass BSP extension pipe fittings give you a reliable, leak-resistant solution that threads in cleanly and holds up over time.\u003c\/p\u003e\n\u003cp\u003eEach fitting is machined from solid brass and features BSP (British Standard Pipe) threads. Available in two pipe sizes — 1\/2\" and 3\/4\" — and two configurations — Female × Male (F×M) and Female × Female (F×F) — with body lengths ranging from 42mm (≈1-5\/8\") to 70mm (≈2-3\/4\"). Order in quantities of 1, 2, 4, 8, 10, or 20 pieces to match your project scale.\u003c\/p\u003e\n\u003cp\u003eTypical applications include extending water supply lines behind walls, connecting irrigation manifolds, adapting boiler and heating system pipework, and bridging pipe gaps in compressed air systems — all scenarios where a standard short nipple won't reach and a precise BSP thread extension fitting is the right call.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔵\u003c\/span\u003e \u003cstrong\u003eThread Standard:\u003c\/strong\u003e BSP (British Standard Pipe).
