Whether you're a plumber routing water lines, a DIYer building a garden irrigation system, or a technician assembling an industrial fluid circuit, you need fittings that thread on cleanly, hold pressure, and resist corrosion over the long haul. These stainless steel BSP female pipe fittings are built for exactly that job.\u003c\/p\u003e\n\u003cp\u003eEach fitting is machined from stainless steel with a standard BSP (British Standard Pipe) female thread interior. Available in three pipe sizes — 1\/2\" (DN15), 3\/4\" (DN20), and 1\" (DN25) — and in two connector configurations: 3-way (tee) and 4-way (cross). The 3-way tee splits or merges flow at a single branch point, while the 4-way cross distributes flow in two perpendicular directions. Sold individually (1 pc per order); select your size and configuration from the variant options above.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include residential and commercial water supply lines, garden drip irrigation manifolds, compressed air distribution systems, and light industrial fluid circuits — anywhere a durable BSP female tee or cross connector is needed to branch or combine pipe runs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ② COMPATIBILITY BAR --\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eThread Compatibility:\u003c\/strong\u003e BSP (British Standard Pipe) female thread — fits standard BSP male-threaded pipes, valves, and adapters. \u003cstrong\u003eNot directly compatible with NPT (US National Pipe Thread)\u003c\/strong\u003e without a BSP-to-NPT adapter.

A 4-way fitting (cross connector) has four ports in a + shape, enabling flow to split or merge in two perpendicular directions simultaneously. Choose the 3-way for a simple branch, and the 4-way for a manifold or grid-style layout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow much pressure can these stainless steel fittings handle?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eStainless steel BSP fittings are generally rated for working pressures up to approximately 150 PSI (≈10 bar) in standard residential and light commercial plumbing applications. Actual pressure ratings depend on wall thickness, installation quality, and the fluid being carried. For high-pressure or safety-critical systems, contact us to confirm the specific rating for your chosen size.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use these fittings outdoors or in wet and humid environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. Stainless steel is inherently resistant to rust and oxidation, making these fittings well-suited for outdoor plumbing, garden irrigation systems, and humid indoor environments such as basements or utility rooms. For environments with prolonged saltwater exposure or aggressive chemical contact, confirm the stainless steel grade is appropriate for your conditions before installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these fittings compatible with NPT (US National Pipe Thread) pipes?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo — BSP and NPT threads are not directly interchangeable. BSP threads have a 55° thread angle and different pitch specifications compared to NPT's 60° angle. If your existing pipes or valves use NPT threads, you will need a BSP-to-NPT adapter to connect them. If you are unsure which thread standard your pipes use, a thread gauge or a local plumbing supplier can help you identify them.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need PTFE tape or thread sealant when installing these fittings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes, applying PTFE thread seal tape (plumber's tape) or a suitable pipe thread sealant compound is strongly recommended for all BSP threaded connections. This fills microscopic gaps in the thread engagement and ensures a leak-free seal under pressure. Wrap the male thread 2–3 times clockwise before threading into the female fitting, then tighten with a wrench — do not over-tighten.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat fluids are compatible with these stainless steel BSP fittings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese fittings are generally compatible with water, compressed air, mild oils, and many non-aggressive fluids commonly found in residential and light industrial plumbing.
