What it is

The Potterton COM15601827 is a 3 inch flange gasket rated PN6, used to seal flanged joints on Potterton commercial gas boilers. It sits between the mating flange faces and compresses under bolt load to prevent leakage at the joint. This gasket replaces the earlier code 922129.

Signs this part needs replacing

  • Water weeping or dripping from the flange joint
  • Visible cracking, splitting or perishing of the gasket material
  • Gasket hardened or brittle, losing its sealing compression
  • Scale or corrosion staining around the flange faces
  • Gasket distorted or damaged after the joint has been opened

Before you order

  • Confirm the boiler model against the manufacturer's parts list
  • Check the flange nominal size and pressure class match the joint being sealed
  • Check whether the existing gasket carries the replaced code 922129
  • Confirm how many flange joints require a gasket
