Buderus O-Ring 14.48mm x 2.62mm 7099167

The Buderus 7099167 is an O-ring with a 14.48mm diameter and a 2.62mm cross-section, supplied in a pack of 10. It is a sealing component used at joints and connections within Buderus gas boiler assemblies, where it prevents water or gas from escaping past a mating face. O-rings of this size are typically fitted at smaller unions, tappings and internal connections rather than large flange joints.

• Water weeping or a visible drip at the joint the O-ring seals
• A gas smell or detection at the union, indicating the seal is no longer gas-tight
• The O-ring is visibly flattened, hardened or cracked when the joint is opened
• The O-ring is cut, nicked or has swollen out of shape after removal
• Recurring leaks at the same joint after the union has been tightened

• Measure the old O-ring across its diameter and cross-section to confirm it matches 14.48mm x 2.62mm
• Identify the boiler model from the appliance data badge to confirm it appears in the fit list
• Check how many joints are being resealed, as the pack contains 10 O-rings
• Confirm the O-ring material is suitable for the medium and temperature at the point of fitment
