What it is

The Buderus O-Ring 19mm x 3mm (Pack 5) is a sealing component for compatible Buderus gas boiler appliances. It is used to create a fluid-tight seal at joints and connections within the boiler. This pack contains five O-rings.

Signs this part needs replacing

  • Visible cracks, splits or cuts in the O-ring.
  • The O-ring feels hard, brittle or has flattened.
  • Water weeping or dripping from the sealed joint.
  • Scale, rust or debris around the seal area.
  • A leak that persists after the joint has been tightened.

Before you order

  • Confirm the O-ring dimensions are 19mm x 3mm.
  • Check the appliance model against the compatibility list.
  • Check how many O-rings the repair requires.
  • Inspect the mating surfaces for damage or corrosion before fitting.
