  • Galvanized malleable iron resists corrosion in water systems
  • Rated 300 psi at 150 °F for high-pressure lines
  • Meets ASME B16.3 and B16.4 plus ASTM A197 and A47
  • NSF-61 and AB1953 listed for potable water use

Reducing Tee 3/4" x 3/4" x 1/2" FNPT

This galvanised malleable iron reducing tee connects three female NPT pipes at a Class 150 rating. It meets ASME B16.3 and B16.4 standards along with ASTM A197 and A47 specifications. The fitting carries FM, NSF-61, AB1953 and UL listings for potable water and fire protection use. It is supplied new for residential and commercial plumbing installations.

Branch Size 1/2 Inch FNPT

The 1/2 inch branch outlet is the single dimension that determines whether this tee matches the required take-off point. Both run ends are 3/4 inch FNPT so the branch must align with the smaller pipe or valve being added. Verify the branch size against the system design before purchase.

Class 150 Galvanised Iron Fitting

Rated for 300 psi water, oil or gas at 150°F and 150 psi saturated steam, this tee threads directly onto matching FNPT pipe ends without welding. The galvanised coating resists corrosion in water supply lines. Installers must provide compatible 3/4 inch and 1/2 inch male NPT pipe nipples or valves to complete the assembly.

Questions about this item

What does the 300 psi WOG rating mean once the tee is installed in a water, oil or gas line?

It indicates the maximum non-shock working pressure of 300 psi at 150 °F for water, oil or gas service.

Which standards govern the threads and material, and what do they cap in practice?

ASME B16.3 and B16.4 cover dimensions and pressure classes for Class 150 malleable iron fittings, limiting this tee to 300 psi WOG and 150 psi saturated steam.

What pipe sizes and thread type are needed to connect the three outlets?

The run outlets take 3/4 in FNPT pipe and the branch takes 1/2 in FNPT pipe, all female National Pipe Taper threads.
