What it is

A Buderus O-ring measuring 59 x 3mm and manufactured in NBR70 nitrile rubber. It is supplied as a 2-piece kit for CG15/20 applications and forms the sealing element at the joint it is fitted to. The O-ring is listed for use on Buderus GB312-200 appliances and referenced under part number 63020361.

Signs this part needs replacing

  • Visible weeping or moisture tracking at the sealed joint
  • Water loss or pressure drop that returns after topping up
  • The O-ring feels hard, flattened or brittle rather than pliable
  • Cracking, splits or a squared-off cross section visible on inspection
  • Scale or debris build-up on the sealing face after a joint is disturbed

Before you order

  • Confirm the existing O-ring measures 59 x 3mm before ordering
  • Check the appliance model against the fit list above
  • Confirm NBR70 nitrile rubber is suitable for the fluid and temperature at the joint
  • Note that the kit contains 2 pieces, so check how many joints are being resealed
