Plumbers, HVAC technicians, irrigation installers, and DIY homeowners rely on these compact fittings to connect mismatched thread sizes cleanly and securely in water, air, and fluid systems.\u003c\/p\u003e\n\u003cp\u003eEach piece is a solid brass hexagon bush with a male BSP thread on the outside (larger diameter) and a female BSP thread on the inside (smaller diameter). Available in a wide range of size combinations from 1\/8\" male × 1\/8\" female up to 2\" male × 1-1\/2\" female, covering the most common reducing steps used in residential and light commercial plumbing. The hex body provides flat wrench surfaces for controlled installation without slipping.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include reducing a 3\/4\" BSP supply line down to a 1\/2\" BSP valve inlet, stepping a 1\" BSP manifold port to a 3\/8\" BSP instrument connection, and adapting 1-1\/4\" or larger mains pipework to smaller branch fittings — all common scenarios in home plumbing upgrades, workshop air systems, and garden irrigation setups.\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) — parallel thread (BSPP \/ G-thread).
