Goraguchi 2pcs Brass Water Meter Coupling 3/4″ BSP x NPT

The Goraguchi brass water meter coupling provides a reliable bridge between 3/4″ BSP female and 3/4″ NPT male pipe threads. Each set includes two hex‑nipple adapters and a pre‑installed seal washer, ensuring a leak‑free connection without the need for additional sealing components. Constructed from durable brass, the fittings resist corrosion, maintain high‑temperature ductility, and exhibit low magnetic permeability, making them ideal for both residential and commercial water service systems.

Designed for demanding applications, these couplings are rated for a maximum working pressure of 300 PSI and can operate safely across a wide temperature spectrum—from –65 °F (–54 °C) up to 250 °F (121 °C). The robust construction and precise threading allow seamless integration of disparate pipe sections, helping you extend or modify your water distribution network with confidence. Whether you are upgrading an existing meter line or installing a new system, these brass adapters deliver consistent performance and long‑term durability.
