This brass BSP 3\/4\" male thread extension nipple is designed for installers, maintenance technicians, and serious DIYers who need a dependable, thread-accurate connector the first time.\u003c\/p\u003e\n\u003cp\u003eEach piece is machined from solid brass with BSP (British Standard Pipe) 3\/4\" male threads on both ends, available in five lengths: 32mm (≈1-1\/4\"), 35mm (≈1-3\/8\"), 50mm (≈2\"), 70mm (≈2-3\/4\"), and 100mm (≈3-15\/16\").
