What it is
The Baxi 7683973 is a kit of O-rings for the expansion vessel pipe on Baxi boilers. It is classed as a gasket, O-ring, seal and washer, and its job is to seal the expansion vessel pipe connection so the heating system holds its pressure.
Before you order
- Confirm your boiler model and full serial number, as fitment varies by serial number ending.
- Check the boiler's gas type (natural gas or LPG) against the fit list.
- Note that the kit is for the expansion vessel pipe connection, so check that this is the seal you need to replace.
