What it is

The Potterton 670176 is a 24 x 18 washer with a 3/4 inch connection, supplied as a boiler spare for Potterton gas appliances. It is used across the Combi, Puma and Suprima ranges, where it forms a seal at a 3/4 inch joint.

Signs this part needs replacing

  • Water weeping or dripping from the joint the washer seals
  • The washer is visibly flattened, cracked or perished
  • Scale or corrosion build-up on the washer face
  • Unexplained pressure loss traced back to the joint
  • A leak that returns after the connection is tightened

Before you order

  • Confirm the part number 670176 matches the number listed for your appliance
  • Check your boiler model against the fit list above
  • Inspect the mating faces of the joint for damage before refitting
  • Check whether other seals in the same joint also need replacing
