Vaillant O-Ring Pack Of 10 0020143467

A pack of 10 O-rings manufactured by Vaillant, part number 0020143467. These seals are used on Vaillant ecoTEC VU GB 1006/5-5 and 1206/5-5 R2 and R3 appliances, where they form a watertight joint at the point of fitment. Supplied as a multi-pack so a full service or repair can be completed without reordering.

• Visible water weeping or a damp trace around the joint the O-ring seals
• The O-ring has hardened, flattened or cracked with age and no longer sits proud of its groove
• A joint that continues to seep after the fitting has been tightened to specification
• Scale or debris embedded in the seal face, preventing a clean seal
• Recurring pressure loss traced to a sealed connection rather than the pipework

• Confirm the appliance model and GC number against the fitment list above
• Check whether the boiler is an R2 or R3 variant, as both are covered by this pack
• Inspect the joint before ordering to confirm the O-ring, rather than the fitting itself, is the cause of the leak
• Note that this is a pack of 10, so check how many seals the job requires
