Stainless Steel BSP Tee Fittings 1/2" & 3/4" Male Female Reducer Connector

BSP sizes refer to the nominal bore of the pipe, not the outer diameter. A 1/2" BSP fitting typically has an outer thread diameter of approximately 20.9mm (≈0.82"), while a 3/4" BSP fitting is approximately 26.4mm (≈1.04"). Measure your existing pipe thread or use a thread gauge to confirm the size before ordering. When in doubt, contact us — we can help you identify the right variant.

Stainless steel BSP fittings of this type generally support working pressures in the range of 150–300 PSI depending on the specific configuration, wall thickness, and installation conditions. For high-pressure or safety-critical applications, please contact us to confirm the exact pressure rating for your chosen variant before installation.

Yes. Stainless steel construction provides strong resistance to rust, oxidation, and mild chemical exposure, making these fittings generally suitable for outdoor plumbing, marine environments, and humid or wet conditions. For highly aggressive chemical environments (strong acids, chlorinated solutions), contact us to confirm material compatibility with your specific application.

These fittings use BSP (British Standard Pipe) threads, which are commonly used in the UK, Australia, Asia, and many international plumbing systems. BSP threads are not directly compatible with NPT (National Pipe Taper) threads used in North American systems. If your existing pipes use NPT threads, you will need a BSP-to-NPT adapter fitting.

A T-tee (standard tee) splits flow at a 90° angle and is the most common choice for branching a main supply line. A Y-tee splits flow at approximately 45° on both branches, reducing turbulence and pressure drop — commonly used in drainage and low-resistance flow applications. A 45° tee offers an angled branch connection, useful when space constraints prevent a straight 90° branch off the main line.

Stainless steel BSP fittings are generally used in water, air, and hydraulic fluid systems. For gas line applications, local codes and regulations typically require fittings that are specifically rated and certified for gas use. Always verify with a licensed plumber or gas fitter and check local building codes before installing any fitting on a gas line.

Male (M) ports have external threads that screw into a female-threaded socket or fitting. Female (F) ports have internal threads that accept a male-threaded pipe or fitting. The variant names (e.g., Female&Female&Female or Male&Female&Male) describe the thread type on each of the three ports of the tee in order — Port 1 & Port 2 & Port 3.

Yes. BSP parallel threads (BSPP) require PTFE tape or a thread sealant compound to achieve a leak-free seal, as the thread form itself does not create a pressure-tight seal by taper alone. Apply 2–3 wraps of PTFE tape to male threads in the direction of the thread before assembly. BSP tapered threads (BSPT) may seal on the taper, but PTFE tape is still recommended for best results and to prevent galling on stainless steel threads.
