SS 304 90° BSP Elbow Fitting | Male-Female 1/8" to 2" Pipe Connector

Match the fitting size to your existing pipe's nominal bore, not its outer diameter. BSP sizes are nominal — for example, a 1/2" BSP (DN15) pipe has an actual OD of approximately 20.9 mm (0.825"). Check the thread on your existing pipe or valve with a thread gauge, then select the matching size from the variant options above. Reducer variants are also available if you need to step up or down between two pipe sizes.

These fittings are made from 304 stainless steel, which generally offers a tensile strength of around 515 MPa (75,000 psi) and a yield strength of approximately 205 MPa (30,000 psi). They are suitable for typical residential and light commercial plumbing pressures. For high-pressure industrial applications, please contact us to confirm suitability.

Yes. 304 stainless steel is corrosion-resistant and performs well in outdoor, humid, and wet environments. It is generally suitable for fresh water, air, and mild chemical exposure. For marine or highly chlorinated environments, 316 stainless steel is typically recommended instead.

No — BSP and NPT threads are not directly interchangeable. BSP uses a 55° thread angle, while NPT uses a 60° angle, and the thread pitches also differ. Using a BSP fitting on an NPT pipe (or vice versa) will result in leaks. Always confirm your existing pipe uses BSP threads before ordering.

Yes — applying PTFE thread seal tape (plumber's tape) to the male threads before assembly is strongly recommended to ensure a leak-free connection. Wrap the tape clockwise around the male thread 2–3 times before threading the fitting in by hand, then tighten with a wrench. Do not overtighten, as this can crack or distort the fitting.

Standard variants (e.g., 1/2" Male & Female) have the same BSP size on both ends — ideal for a straight 90° direction change in the same pipe size. Reducer variants (e.g., 1/2" Male to 3/4" Female) have different sizes on each end, allowing you to change direction and step up or down to a different pipe diameter in a single fitting, saving space and reducing the number of joints.

304 stainless steel BSP elbow fittings are generally compatible with water, air, steam (at appropriate pressure ratings), and many mild chemicals. They are commonly used in water supply lines, compressed air systems, and irrigation pipe runs. For aggressive chemicals, oils, or food-grade applications, please contact us to confirm compatibility before ordering.
