ZORO SELECT 1/2" Malleable Iron Tee

This ZORO SELECT tee joins three 1/2 inch FNPT pipes in a water, oil or gas system. It is made from black malleable iron rated to Class 150 and carries UL and FM approvals. The fitting meets ASTM A-197, ASTM A47, ASME B 16.3 and B 16.14 standards.

Installers needing a 150 psi saturated-steam rating

The part handles 300 psi at 150 °F WOG and 150 psi saturated steam, so it suits residential and light-commercial piping. It is not for systems that exceed the Class 150 pressure envelope or that require a different thread standard. Buyers needing a larger bore or a different material should select another fitting.

Class 150 pressure rating at 300 psi WOG

This single rating defines whether the tee matches the design pressure of the circuit. If the system works above 300 psi water, oil or gas at 150 °F, the fitting is not suitable. Verify the required class before ordering.

Questions about this item

What thread size does the 1/2" FNPT tee require for pipe connections?

The tee uses 1/2 inch FNPT threads on all three ports for direct pipe engagement.

How do you seal the NPT threads during installation without cracking the malleable iron?

Apply PTFE tape or pipe dope sparingly, hand-tighten, then turn one to two full turns with a wrench — over-torquing splits the casting.

When should the Class 150 tee be replaced if used on saturated steam lines?

Replace it if pressure exceeds 150 psi saturated steam or if visual inspection shows cracks, corrosion or thread deformation.
