What it is

The Potterton 5106032 is a silicone O-ring seal used on Powermax HE condensing boilers. It sits in a joint face within the appliance to prevent water loss from the sealed connection. The supplied product name records the size as 222mm x 4.0mm, while the catalogue listing for the same part number gives 22mm x 4mm, so the old seal should be measured before ordering.

Signs this part needs replacing

  • Weeping or dripping at the joint the O-ring seals
  • Damp staining or water marks around the seal seating area
  • Seal visibly flattened, hardened or deformed
  • Cracks, splits or a squared-off cross section on the ring
  • Scale or corrosion debris found on the seal or in its groove

Before you order

  • Measure the old O-ring's internal diameter and cross section and compare it with the size quoted for the part
  • Confirm the appliance model is a Powermax HE85, HE115 or HE150
  • Inspect the seal groove and mating faces for damage before fitting a new ring
