What it is

This is a Potterton O-ring with an internal diameter of 5.3mm and a cross-section of 2.4mm, supplied in a pack of two. It is a sealing component used on Potterton Promax 24 Store cylinder ErP appliances. The O-ring provides a fluid-tight seal at the point where it is fitted.

Signs this part needs replacing

  • Visible cracking, flattening or perishing of the O-ring material
  • Water weeping or dripping from the joint the O-ring seals
  • Scale or debris deposits around the sealing face
  • The O-ring has been disturbed during servicing and no longer seals correctly

Before you order

  • Confirm the existing O-ring measures 5.3mm x 2.4mm before ordering
  • Check the appliance model and serial number against the fitment list
  • Note that this item is supplied as a pack of two, so check how many seals the job requires
  • Inspect the sealing face for damage or scale that could prevent a correct seal
