SKU CH-1R45-AYRF5

A 2 in nominal threaded flange with 5 1/2 in outside diameter, four bolt holes and 300 psi rating

  • Threaded flange rated for 300 psi maximum operating pressure
  • Malleable iron construction meets A197 material standard
  • Zinc-plated finish provides corrosion resistance
  • Four bolt holes simplify pipeline alignment
  • Class 150 pressure class suits standard plumbing systems

Zoro Select 5 1/2 in Threaded Flange

This Zoro Select flange provides a 2 in nominal pipe size connection with a flanged by FNPT design. The 5 1/2 in outside diameter suits standard piping layouts. It is intended for installers joining threaded pipe to a flanged joint.

Malleable Iron Construction With Zinc Plating

The body uses A197 malleable iron with a zinc-plated finish for corrosion resistance. Class 150 rating supports a 300 psi maximum operating pressure in normal service. Four bolt holes allow secure mounting to a mating flange.

Replaces Worn Or Damaged Threaded Flanges

This unit replaces a corroded or cracked flange on existing 2 in nominal pipe systems. The upgrade is worth it when the old flange leaks at the bolt circle or threads. It is not for installers needing a different nominal size or pressure class.

Questions about this item

How do I thread the 2 in NPT side of this flange without cross-threading the malleable iron?

Start the flange by hand on clean NPT threads, turning clockwise until resistance is felt, then tighten with a strap wrench on the 5 1/2 in OD — never use a pipe wrench directly on the zinc-plated body.

Will the zinc plating on this Class 150 flange need recoating after installation?

The zinc plating protects the malleable iron during storage and assembly; once sealed with PTFE tape or pipe dope on the threads, no recoating is required unless the plating is mechanically damaged.

At what pressure does the 300 psi rating of this A197 flange become the limiting factor in a steam line?

The 300 psi maximum operating pressure is the first limit reached under sustained steam service; do not exceed it, and verify system relief valves are set below this value.
