What it is
Worcester Bosch O-ring, part 8716121863, measuring 9.5 x 2.5 mm. It is a single rubber sealing ring used to seal a joint on Greenstar 4000 System and Gr4700IW appliances. The O-ring compresses between mating faces to prevent water or gas escaping from the joint it sits in.
Signs this part needs replacing
- Water weeping or dripping from the joint the O-ring seals
- Visible flattening, hardening or cracking of the ring once the joint is opened
- Scale or corrosion debris sitting in the seal groove
- Repeated loss of pressure at a joint that has already been resealed
Before you order
- Confirm the appliance model and GC number against the fit list above
- Check the size of the O-ring being removed, as more than one size is used across the appliance
- Check whether more than one O-ring is needed for the joint being worked on
