Stainless Steel BSP Reducer 90° Elbow Fittings — 1/8" to 1" Male & Female

Identify the BSP thread size on both the inlet and outlet ports of your existing pipes or valves. The first size listed in the variant name is the larger (inlet) port; the second is the smaller (outlet) port. For example, "1/2" Female to 1/4" Female" connects a 1/2" female-threaded pipe to a 1/4" female-threaded port at a 90° angle. When in doubt, measure the outer diameter of the male thread and compare to a BSP thread chart — a 1/2" BSP male thread is typically about 20.9mm (≈0.82") in outer diameter.

These fittings are generally manufactured from 304 stainless steel, which provides good corrosion resistance for most water, air, and light fluid applications. If your application involves highly aggressive chemicals or prolonged saltwater immersion, contact us to confirm the exact alloy grade for your specific variant.

Yes. Stainless steel BSP fittings are typically suitable for outdoor and damp environments. They resist rust and surface oxidation far better than carbon steel or uncoated brass alternatives. For prolonged coastal or saltwater exposure, applying PTFE thread tape and ensuring proper drainage will extend service life.

Yes. These reducer elbows use BSPP (British Standard Parallel Pipe) threads, the most common BSP standard used worldwide. They are compatible with other BSPP fittings, valves, and pipe connectors. Important: BSP threads are not directly interchangeable with NPT (National Pipe Taper) threads commonly used in North America — you will need a BSP-to-NPT adapter if connecting to NPT-threaded components.

Stainless steel BSP fittings of this type are generally rated for working pressures in the range of 150–300 PSI depending on port size and wall thickness. Smaller port sizes typically handle higher pressures. For safety-critical or high-pressure systems, contact us to confirm the rated pressure for your specific variant before installation.

Yes. BSPP threads are parallel (not tapered), so they rely on a face seal, O-ring, or thread sealant to achieve a leak-free connection — the threads alone do not seal. Always wrap male threads with PTFE tape (2–3 wraps) or apply a compatible thread sealant compound. Do not overtighten — hand-tight plus 1–2 turns with a wrench is generally sufficient for most applications.

Female outlet variants have an internal thread on the outlet port — you thread an external (male) pipe or fitting into them. Male outlet variants have an external thread on the outlet port — they thread into an internal (female) port on your valve, manifold, or pipe. Choose based on the thread type of the component you are connecting to on the outlet side.
