What it is
The Vaillant 981151 O-ring is a sealing component supplied in a pack of ten. It is used across a range of Vaillant gas boilers, including Turbomax, Ecomax, Thermocompact, Aquaplus and Ecotec Exclusive models, to seal joints within the appliance and prevent leaks. Fitting a new O-ring restores a watertight seal where the existing one has hardened, flattened or perished.
Signs this part needs replacing
- Water weeping or dripping from a joint sealed by the O-ring
- Visible cracking, flattening or hardening of the O-ring
- Scale, corrosion or staining around the seal
- Repeated loss of system pressure requiring regular top-ups
- Damp marks on components below the joint
Before you order
- Confirm your boiler model and GC number against the fitment list above
- Check the position and quantity of O-rings required for the joint being repaired
- Isolate the appliance and depressurise the relevant circuit before fitting
