What it is
The Baxi 5118289 is a single lip seal with a 60mm diameter, moulded in EPDM rubber. It is used on Baxi and Potterton HEAT boiler ranges to seal a joint against water or flue-side leakage. EPDM is chosen for its resistance to heat ageing and water exposure in this position.
Signs this part needs replacing
- Water weeping or a visible drip trail around the seal seating
- The lip has hardened, flattened or lost its elasticity
- Cracking, splitting or perishing visible on the seal face
- Scale or corrosion deposits built up on or behind the lip
- Discolouration or staining on the surrounding casing or joint
Before you order
- Confirm your boiler model and, where applicable, the serial number range against the fit list above
- Check the existing seal measures 60mm across to match this part
- Inspect the mating face for pitting, scale or corrosion before fitting a new seal
- Check whether any other seals or gaskets on the same joint also need renewing
