Stainless steel tee fittings are supplied in different grades to suit specific pressure, temperature, and media conditions. The grade of stainless steel determines the corrosion resistance, mechanical strength, and temperature capability of the tee. We supply stainless steel tees in the following grades:
All stainless steel tees we supply are accompanied by Material Test Certificates (MTC) confirming the exact grade, mechanical properties, and heat number — ensuring full traceability and compliance with international project specifications.

Correct stainless steel tee selection is critical to ensuring a leak-free piping system and long-term operational safety. The tee type, grade, and end connection must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing a stainless steel tee:
If you are unsure which stainless steel tee specification best suits your application, our technical team is available to review your piping drawings, process data, and project specifications — and recommend the most suitable stainless steel tee solution.

Stainless steel tee fittings are pipe components used to branch a piping system. They have three openings — one on the run and one on the branch. They are manufactured from stainless steel grades such as SS304, SS316, SS321, SS347, and SS904L for corrosion resistance and high-temperature performance.
We supply stainless steel equal tees, reducing tees, and barred tees (pipeline tees) in butt weld, socket weld, and threaded configurations — in various grades, sizes, and schedules per project specifications.
