201 Stainless Steel Equal BSP Thread Tee — Branch Your Pipe Run in Any Direction
Whether you're splitting a water supply line to feed two fixtures, adding a branch to an existing pipe run, or building out an irrigation manifold, finding a BSP equal thread tee fitting that matches your exact port configuration can be a real challenge. Plumbers, contractors, and DIY homeowners all face the same issue: needing a T-shape connector where each port is the right thread type — male or female — for the pipes already in place. These 201 stainless steel equal BSP thread tee connectors cover the most common 1/2", 3/4", and 1" configurations in both all-female, all-male, and mixed thread arrangements.
Each fitting is a three-port equal tee machined from 201 stainless steel, with all three ports the same nominal BSP size. Available in 1/2" (DN15), 3/4" (DN20), and 1" (DN25) BSP, with eight thread configurations covering all-female (F×F×F), all-male (M×M×M), and mixed combinations (F×M×M, F×F×M, F×M×F, M×F×M). Sold in quantities of 1, 2, 3, 5, or 10 pieces — select both your size/configuration and quantity from the variant options above.
These equal tee fittings are well suited for residential water supply line branching where a single pipe needs to feed two outlets, for irrigation system manifolds connecting a main supply to multiple zone valves, and for light industrial fluid distribution where a stainless steel BSP tee is needed for corrosion resistance in damp or wet environments. The equal-port design ensures balanced flow across all three branches.

Thread Compatibility: BSP (British Standard Pipe) threads only — available in male and female configurations. Not compatible with NPT threads. Confirm your pipe system uses BSP before ordering, and select the correct M/F configuration for each port.
⚠️
Material Note: These fittings are made from 201 stainless steel, which is more economical than 304 but has lower nickel content and reduced corrosion resistance. Suitable for indoor plumbing and sheltered applications. For outdoor, marine, or chemically aggressive environments, consider 304 or 316 stainless steel fittings.

❓ Frequently Asked Questions
How do I choose between male and female thread configurations?
Match each port to the fitting or pipe it will connect to. A female (F) port accepts a male-threaded pipe or fitting; a male (M) port screws into a female-threaded socket or valve. For example, if all three pipes in your system have male BSP threads, choose the all-female (F×F×F) variant. If two pipes are female-threaded and one is male, choose the corresponding mixed configuration. When in doubt, check the thread type on each pipe end before ordering.
What is the difference between 201 and 304 stainless steel for pipe fittings?
201 stainless steel contains less nickel than 304, making it more economical but generally less corrosion-resistant. It is suitable for indoor plumbing, water supply lines, and low-humidity environments. For outdoor, marine, or chemically aggressive applications, 304 or 316 stainless steel is typically recommended. If your installation is in a sheltered indoor location, 201 SS is generally adequate for standard water line use.
Can these tee fittings be used outdoors?
201 stainless steel offers moderate corrosion resistance and is generally suitable for sheltered outdoor use where direct moisture exposure is limited. In environments with prolonged moisture, salt air, or chemical exposure — such as coastal locations or industrial settings — 304 or 316 stainless steel fittings are typically a more durable long-term choice.
Are these fittings compatible with NPT threads?
No — these fittings use BSP (British Standard Pipe) threads, which are not interchangeable with NPT (National Pipe Thread). BSP uses a 55° thread angle while NPT uses 60°, and the thread pitches also differ. Mixing BSP and NPT fittings can result in cross-threading or leaks. Always confirm your pipe system uses BSP threads before ordering.
What pressure can these tee fittings handle?
Pressure ratings for 201 stainless steel BSP tee fittings vary by size and wall thickness. They are generally suitable for standard residential water supply pressures (typically up to 100–150 PSI). Larger sizes generally have lower pressure ratings than smaller sizes. For high-pressure or industrial applications, contact us to confirm suitability before ordering.
Do I need thread sealant with these fittings?
Yes. BSP threaded fittings typically require PTFE tape (plumber's tape) or thread sealant compound to achieve a leak-free seal. Apply 2–3 wraps of PTFE tape to the male threads in the direction of the thread before assembly. Hand-tighten first, then use a wrench for final torque — avoid over-tightening, which can crack or deform the fitting.
Can I buy these in bulk for a project?
Yes. These BSP tee fittings are available in quantities of 1, 2, 3, 5, and 10 pieces per order. Select your preferred quantity from the Amount option above. Ordering in larger quantities reduces the per-unit cost, making it practical for multi-fixture plumbing installations, irrigation projects, or keeping spares on hand.
