Stainless Steel Reducing Welded Lateral Y type Tee

Welded Lateral Y type Tee is a special oblique three-way pipe fitting with a 45° lateral branch and welded connection, Sanitary tee widely used in 45 Degree sanitary, industrial, oil, chemical and food-grade pipelines. It is installed at oblique branching or diverging positionstosplit, divert or converge fluid smoothly with low turbulence and reduced pressure loss. Common types include equal welded lateral Y tee, reducing welded lateral Y tee, 304/316L stainless steel welded lateral Y tee, and high-pressure welded lateral Y tee, featuring strong welding integrity and stable flow performance.

Welded Lateral Y type Tee features a 45° oblique lateral branch for smooth flow diversion, while standard tees use a 90° T‑shape that creates high turbulence. Its welded connection ensures stronger integrity and zero leakage. Our products adoptCNC precision forming, full polishing, and high‑grade 304/316L stainless steel with strict pressure testing. Compared with others, our welded lateral Y tee provides lower pressure loss, better flow stability, higher durability, and cleaner hygienic performance, ideal for high‑demand industrial and sanitary pipelines.
