Chaffoteaux O-Ring D: 6.4mm x 1.9mm 60021061-11

The Chaffoteaux 60021061-11 is a small O-ring with dimensions of 6.4 mm x 1.9 mm. It is a sealing component used within the hydraulic and gas-carrying assemblies of Chaffoteaux Celt Star boilers, where it prevents leaks at a joint face. The ring is compressed between mating surfaces to form a fluid-tight seal.

• Visible water or gas weeping at the joint the ring seals
• The O-ring is flattened, hardened or cracked when inspected
• The ring has swollen or stretched and no longer sits correctly in its groove
• Traces of scale, corrosion or debris on the sealing face after a leak
• A joint that continues to seep after the assembly has been re-tightened

• Confirm the part number 60021061-11 against the boiler's parts list
• Check the appliance model against the fit list above
• Measure the old O-ring to confirm the 6.4 mm x 1.9 mm dimensions
• Inspect the sealing faces and groove for damage before fitting a new ring
