Black forged steel tee with three socket weld ports

Zoro Select

Zoro Select 1MNR3 Tee 1" Socket Weld Black Forged Steel Class 3000

SKU CH-60CN-M0XDQ

Connects three 1-inch pipes with a black forged steel socket-weld tee rated to Class 3000

  • Forged steel construction handles Class 3000 pressure
  • Black oxide finish resists corrosion in piping systems
  • Three 1" female socket-weld ends simplify branch connections
  • 11 1/2 thread specification ensures standard fit
  • Zoro Select brand backs consistent manufacturing quality

Application Fit

The Zoro Select 1MNR3 is a forged-steel tee designed for socket-weld piping systems. It suits installers and maintenance crews building or repairing 1-inch black-oxide lines in industrial or commercial settings. Buyers needing threaded, butt-weld or flanged connections will need a different fitting type.

Pressure Class and Flow Capacity

Rated to Class 3000, the fitting handles the pressure demands of standard high-pressure steam, oil, gas and water services. The 1-inch bore with 11 1/2 socket ends on all three outlets provides full-flow passage for typical process media. Systems requiring a higher pressure class or a larger nominal size exceed this component's rating.

Socket-Weld Installation Limits

Socket-weld joints demand precise pipe preparation and skilled welding to meet code requirements. The design is permanent once welded, so layout changes require cutting and replacement. Installers without certified socket-weld procedures or those working in systems that mandate threaded or flanged joints cannot use this tee.

Questions about this item

Will the 1 inch socket weld ends fit existing Class 3000 forged steel piping I already have?

Yes, each of the three outlets is a 1 inch female socket weld designed for Class 3000 forged steel pipe, so it matches the same pressure class and connection type.

How can I verify the tee is seated correctly after welding?

After socket welding, inspect each joint for full penetration and uniform fillet around the 1 inch bore, then pressure test the assembly to the Class 3000 rating before service.

Does the package include any gaskets, bolts or sealant for the socket weld connections?

The tee is supplied as a single forged steel fitting with black oxide finish; socket weld joints require only compatible pipe and welding consumables, which are sold separately.
