What it is
The Baxi 7660851 is a locking pin for the air vent assembly, sized for 18mm tube. It secures the air vent component on Baxi combi and system ErP boilers, holding the vent body in position on the pipework. The pin is a small consumable item that forms part of the air vent arrangement on the appliance.
Signs this part needs replacing
- The pin is missing, so the air vent body is not held securely on the tube
- Visible corrosion or pitting on the pin
- The pin is loose in its location and will not seat properly
- Weeping or dripping at the air vent where the pin no longer holds the assembly correctly
- The pin has been damaged or bent during previous service work
Before you order
- Confirm the appliance model and the serial number suffix, as fitment is listed against specific serial number endings
- Check the part number 7660851 against the appliance's parts list
- Confirm the air vent is fitted to 18mm tube before ordering
- Inspect the surrounding air vent assembly for any further damage that may also need attention
