Ariston O-Ring 18.4mm x 2.7mm 60024164-22

This is an O-ring supplied by Ariston under part number 60024164-22, measuring 18.4 mm x 2.7 mm. It is a sealing component used within the hydraulic and gas-carrying assemblies of Ariston Combi A MFFI gas boilers, where it seats between mating faces to prevent leakage. O-rings of this type are consumable items and are typically renewed whenever the joint they seal is disturbed.

• Visible water weeping or a drip trail around the joint the O-ring seals
• The O-ring is flattened, hardened or has taken a permanent set
• Cracking, splitting or surface perishing on the ring
• Scale or corrosion deposits sitting on the sealing face
• A joint that continues to seep after the assembly has been re-tightened

• Confirm your boiler model and, where applicable, the GC number against the fitment list above
• Measure the old O-ring across its diameter and cross-section before ordering, as more than one size is used across the range
• Check how many O-rings are required for the joint being worked on, as this listing covers a single ring
• Inspect the mating faces for scoring or corrosion, which will cause a new O-ring to leak regardless of size
