What it is
The Ravenheat 0013ORI11020/0 is a pump and expansion vessel O-ring measuring 9.19mm x 2.62mm. It is manufactured by Ravenheat for use in their gas boiler range. The O-ring seals the joint at the pump or expansion vessel connection, preventing water loss from the system.
Signs this part needs replacing
- Water weeping or dripping from the pump or expansion vessel joint
- Visible cracking, flattening or perishing of the O-ring
- The O-ring feels hard or brittle rather than flexible
- Scale or corrosion deposits around the sealing face
- Boiler pressure dropping and needing frequent topping up
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the existing O-ring dimensions (9.19mm x 2.62mm) match
- Inspect the sealing face for damage or debris before fitting
- Isolate the appliance and depressurise the system before removing the old O-ring
