What it is

The Ravenheat ORI150100 is an O-ring for the primary heat exchanger on compatible Ravenheat boilers. It seals the joint at the heat exchanger connection, preventing water loss from the primary circuit. It is a small consumable part that should be renewed whenever the joint is disturbed.

Signs this part needs replacing

  • Water weeping or staining around the primary heat exchanger connection
  • Visible cracking, flattening or hardening of the existing O-ring
  • Loss of primary circuit pressure with no other obvious cause
  • The O-ring has been removed or disturbed during heat exchanger work
  • Scale or debris build-up on the sealing face after draining down

Before you order

  • Confirm the boiler model and GC number against the manufacturer's parts list
  • Check whether the joint uses one O-ring or several before ordering
  • Inspect the sealing faces for corrosion or pitting that could prevent a seal
  • Have the correct washers and seals to hand if the connection is being opened
