Baxi O-Ring 26.64mm x 2.62mm 248434

The Baxi O-Ring 26.64mm x 2.62mm, part number 248434, is a circular elastomer seal used to make a watertight joint between two mating faces inside Baxi combi boilers. It is a direct replacement spare for the ErP Combi and Maxflow Combi FS ranges, sitting in a machined groove or recess where components are clamped together. Measuring 26.64mm by 2.62mm, it compresses under load to close the gap between the surfaces and stop water escaping at the joint.

• A damp trace, weep or slow drip around the joint the ring seals
• The ring looks flattened, hardened or cracked when the joint is opened
• Scale, sludge or debris embedded in the seal face
• Unexplained pressure loss traced back to the affected connection
• The ring stretches, splits or breaks up on removal during another repair

• Check the GC number on the appliance data badge against the list above before ordering.
• Older stock or documentation may carry the previous number 249468; 248434 is the current reference.
• Inspect adjacent seals and washers while the joint is open, as they may need replacing at the same time.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
