3/4/5-Way BSP Female Pipe Fitting Splitter in 304 Stainless Steel — Split One Line Into Multiple Branches Without Losing Flow

Running a single water supply line to multiple zones, or distributing compressed air to several tools from one compressor outlet, means you need a manifold fitting that threads on cleanly, holds pressure across every port, and won't corrode after a season of use. Whether you're a plumber designing a multi-zone irrigation header, a fabricator building a compressed-air distribution manifold, or a DIYer splitting a garden water supply into several drip lines, a poorly made multi-way connector is the first place a system fails.

Each fitting is machined from 304 stainless steel (18/8) and features equal female BSP (British Standard Pipe) threads on all ports, allowing you to split one supply line into two, three, or four branch lines in a single compact body. Available in three port configurations — 3-way, 4-way, and 5-way — and eight BSP sizes per configuration, ranging from 1/4" BSP to 2" BSP, sold individually (1 piece per order). All ports on each fitting share the same thread size, making them true equal-port splitters with no reducers required at the junction.

Typical use cases include multi-zone garden irrigation headers where a single hose bib feeds several drip or spray lines, workshop compressed-air distribution manifolds supplying multiple pneumatic tools simultaneously, and residential or light commercial plumbing systems where a BSP female pipe splitter fitting is needed to branch a hot or cold water supply line to multiple fixtures without additional unions or tees.

🔗 Compatibility: Designed for BSP (British Standard Pipe) threaded systems — BSPP or BSPT. Not compatible with NPT (National Pipe Thread) without an adapter. All ports on each fitting are the same size (equal-port). Confirm your thread standard and port count before ordering.

✅ Key Features of These 3/4/5-Way BSP Female Stainless Steel Pipe Splitter Fittings

🔀 Three Port Configurations in One Listing — Choose 3-way (T/Y), 4-way, or 5-way to match exactly how many branch lines your system requires, without buying separate manifold assemblies.
🔩 Equal Female BSP Threads on All Ports — Every port shares the same BSP thread size, so you can connect same-diameter pipes or hoses to all outlets without reducers or adapters at the junction.
🛡️ 304 Stainless Steel Body — Resists rust, oxidation, and mild chemical exposure; suitable for water, compressed air, and light industrial fluid systems in both indoor and outdoor environments.
📏 Wide Size Range: 1/4" to 2" BSP — Eight sizes per port configuration cover the majority of residential and light commercial pipe fitting applications, from small drip irrigation lines up to 2" main supply headers.
⚙️ Machined Thread Engagement on Every Port — Precisely cut BSP threads on all ports provide consistent torque and a reliable seal when used with PTFE tape or thread sealant compound, reducing the risk of cross-threading or joint failure under pressure.
🌿 Compact Manifold Body for Tight Installations — The single-body multi-port design eliminates the need to chain multiple tee fittings in series, reducing the number of potential leak points and keeping the installation footprint small in confined spaces.

⚠️ Note: BSP and NPT threads are not interchangeable. If your existing system uses NPT fittings, a BSP-to-NPT adapter is required on each port. Not sure which thread standard your pipes use? Measure the thread OD and pitch, or contact us before ordering.

❓ Frequently Asked Questions

How do I choose the right port count — 3-way, 4-way, or 5-way?

Count the number of branch lines you need to feed from a single supply point. A 3-way fitting splits one inlet into two outlets (T or Y configuration). A 4-way fitting provides three outlets from one inlet, and a 5-way fitting provides four outlets. Choose based on how many downstream lines your system requires at that junction point — using a higher port count than needed leaves unused ports that must be capped.

How do I select the correct BSP size for my pipe system?

BSP sizes refer to the nominal bore of the pipe, not the actual thread outer diameter. Match the fitting size to your existing pipe's nominal bore — for example, 1/2" BSP fits pipes with a nominal bore of approximately 15mm (≈0.59"), and 1" BSP fits pipes with a nominal bore of approximately 25mm (≈1"). Measure your existing fitting's thread OD and cross-reference a BSP thread chart to confirm the correct size before ordering.

What pressure can these multi-way BSP fittings handle?

304 stainless steel BSP fittings generally support working pressures up to 150 PSI (approximately 10 bar) for standard water and gas applications. The exact rating depends on pipe wall thickness, temperature, and installation specifics. For high-pressure or steam systems, please contact us to confirm suitability before ordering.

Are these fittings suitable for outdoor or corrosive environments?

304 stainless steel offers good corrosion resistance for most outdoor environments, including freshwater irrigation, mild chemical exposure, and general outdoor plumbing. For coastal or marine environments with high chloride exposure, 316 stainless steel is typically recommended. Contact us if you need marine-grade multi-port fittings.

Are these BSP fittings compatible with NPT threaded pipes?

No — BSP and NPT threads are not directly interchangeable. BSP uses a 55° thread angle while NPT uses 60°, and thread pitches differ between standards. A BSP-to-NPT adapter is required on each port where you need to connect to NPT-threaded components. These fittings are designed for BSP-threaded systems only.

Do I need thread sealant on every port of these multi-way fittings?

Yes — apply PTFE tape or thread sealant compound to every port that will be connected, including any ports you plan to cap. BSPP (parallel) threads rely on a face seal rather than a taper seal, so sealant is required for a leak-free joint. Apply 2–3 wraps of PTFE tape in the direction of the thread on each port before assembly, then hand-tighten and finish with a wrench for 1–2 additional turns.

Can these splitter fittings be used for compressed air distribution?

Yes. 304 stainless steel multi-way BSP fittings are generally suitable for compressed air distribution manifolds in workshop and light industrial settings, provided the working pressure stays within the fitting's rated range. Always verify your system's pressure requirements, use appropriate thread sealant on all ports, and ensure all unused ports are properly capped.
