What it is

The Potterton O-ring 5106237 is a sealing ring measuring 17.86mm x 2.62mm, used on Potterton Promax and Powermax store cylinders and boilers. It seals a water-carrying joint inside the appliance, preventing weeping and drips at the connection. It sits within the O-rings, washers and gaskets group of boiler spares.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • Visible cracking, flattening or perishing of the ring
  • Hardening or discolouration of the rubber
  • Scale or debris build-up on the sealing face
  • A joint that continues to leak after being tightened

Before you order

  • Confirm the appliance model and, where applicable, the serial number against the fit list
  • Check the dimensions of the O-ring removed against 17.86mm x 2.62mm
  • Check whether more than one O-ring is needed for the joint being worked on
