Brass BSP Pipe Fittings – 1" Male Female Thread Connectors, Elbows, Reducers & More

BSP sizing is based on the internal bore of the pipe, not the outer diameter. A 1" BSP fitting typically has an outer thread diameter of approximately 33.25mm (≈1.31"). For reducing fittings, match the larger port to your existing pipe and the smaller port to the line you're connecting. When in doubt, measure your existing fitting's thread OD and compare to a BSP thread chart.

Brass BSP fittings of this type generally handle working pressures up to 150–200 PSI (approximately 10–14 bar) under normal conditions. Actual ratings depend on the specific fitting configuration, wall thickness, and application temperature. For high-pressure industrial use, please contact us to confirm suitability.

Yes. Brass is naturally corrosion-resistant and performs well in outdoor environments, including garden irrigation, hose connections, and rainwater systems. For prolonged exposure to salt air or aggressive water chemistry, applying PTFE thread tape and ensuring proper drainage when not in use will extend service life.

These are BSP (British Standard Pipe) fittings, which use a thread form common in the UK, Europe, Australia, and many Asian markets. BSP threads are not directly compatible with NPT (National Pipe Thread) fittings used in North America without an adapter. Please verify your existing pipe thread standard before ordering.

Yes — for a leak-free seal, apply PTFE (Teflon) thread tape to male threads before assembly. This is standard practice for BSP threaded connections and compensates for minor thread tolerance variations. Pipe dope (thread sealant compound) can also be used as an alternative. Neither is included with the fitting.

• Straight coupling — extends a pipe run in the same direction (male–male or female–female).
• 90° elbow — changes the pipe direction; available in male–female and female–female configurations.
• Reducer — connects two pipes of different diameters (e.g., 1" to 3/4" or 1" to 1/2").
• Union — allows disconnection of the pipe run without cutting, ideal for maintenance access.
• Cap / Plug — seals off an open pipe end; cap fits over female thread, plug screws into female socket.

Brass fittings are generally compatible with hot water applications up to approximately 120°C (248°F) under normal residential plumbing pressures. For steam or high-temperature heating systems, please contact us to confirm the specific fitting's suitability before installation.
