5PCS Brass Meter Coupling 3/4″ BSP Female x 1/2″ NPT Male

Upgrade your water service system with the Goraguchi 5‑piece Brass Meter Coupling set, engineered for seamless integration of disparate pipe standards. Each adapter features a 3/4″ BSP female thread on one end and a 1/2″ NPT male thread on the other, allowing you to bridge British Standard Pipe (BSP) fittings to American National Pipe Thread (NPT) connections without the need for additional adapters or conversion fittings.

Constructed from high‑grade brass, these couplings offer exceptional corrosion resistance, excellent high‑temperature ductility, and low magnetic permeability—ideal for both residential and commercial water infrastructure. The set includes a seal washer with each nipple, ensuring a leak‑free seal and simplifying installation. Designed to withstand pressures up to 300 PSI and operating temperatures ranging from –65°F to 250°F (–54°C to 121°C), these fittings are suitable for a wide range of applications, from municipal water meters to private well systems.

Installation is straightforward: simply thread the BSP female end into the existing pipe or meter, secure the NPT male end to the complementary fitting, and tighten with a hex nipple to compress the seal washer. The durable brass construction guarantees longevity even in harsh environments, while the precise thread design maintains consistent pressure and flow across the junction. Whether you’re expanding a water service line, replacing a damaged segment, or integrating new metering equipment, this 5‑piece set delivers reliable performance and easy compatibility.
