What it is

A pack of two O-rings manufactured by Vaillant, part number 0020142246. The O-ring forms the watertight seal at the joint where it is fitted on the VPM pump unit range. It is a small sealing component, so correct seating and a clean mating face matter as much as the part itself.

Signs this part needs replacing

  • Water weeping or a visible drip at the pump unit joint
  • Damp staining or corrosion tracking around the sealing face
  • The O-ring feels hard, flattened or has lost its round section
  • Cracks, nicks or a split visible on the ring
  • Repeated pressure loss traced to the joint after the system is refilled

Before you order

  • Confirm your appliance model against the fit list above
  • Check whether the joint you are working on takes one O-ring or two, as the pack contains two
  • Inspect the mating faces for scoring or debris before fitting, as this can cause a new seal to leak
  • Have the correct sealing face preparation and torque figures to hand from the manufacturer's instructions
