What it is

A pack of 10 O-rings manufactured by Glow-worm, part number 0020159422. These seals are used on the Glow-worm Energy 35 Store boiler, where they provide a watertight seal at the joints and connections they are fitted to. The pack quantity allows for multiple seals to be replaced during a single service or repair.

Signs this part needs replacing

  • Visible water weeping or dripping from a joint sealed by the O-ring
  • The O-ring is cracked, split or perished
  • The rubber has hardened or flattened, losing its sealing profile
  • Scale or corrosion deposits on the seal or its seating
  • A leak reappears at a joint shortly after the appliance has been serviced

Before you order

  • Confirm your appliance is the Glow-worm Energy 35 Store
  • Check how many O-rings are required for the joint or joints being worked on
  • Compare the removed O-ring against the new part before fitting
  • Inspect the seating surface for damage or debris that could affect the seal
