What it is

The flange joint ring is a gasket supplied by Potterton Commercial for the NXR4 range of commercial boilers. It fits into the flange joint to create a watertight seal between the mating faces. The part is listed as an NXR 4 flange gasket measuring 130 x 170.

Signs this part needs replacing

  • Water weeping or dripping from the flange joint
  • Visible water staining or scale around the mating faces
  • Gasket material cracked, brittle or flattened
  • Repeated loss of system pressure with no other obvious cause
  • Corrosion on the flange faces where the joint has been leaking

Before you order

  • Confirm the appliance is a Potterton Commercial NXR4 and check the section count matches your boiler
  • Check the flange dimensions of 130 x 170 match the joint being sealed
  • Verify the part number COM15601300 against the existing gasket or boiler documentation
  • Isolate and drain the appliance before fitting
