Reducing Tee
The Reducing Tee is a stainless steel fitting designed to connect three pipes—two of the same size and one of a smaller diameter—allowing for a smooth transition in flow direction and volume. Ideal for contractors working on fluid or gas systems, this press-fit tee simplifies branching off a main line to a reduced-size outlet. Installation is fast and flameless: insert each pipe into the fitting and press to seal. Made from corrosion-resistant 304 stainless steel, it’s suitable for demanding environments and a wide range of applications including water, steam, air, and chemical systems.
