Broag O-Ring 720985901

This is a Broag O-ring, manufacturer part number 720985901, supplied to dimensions of 9.19 x 2.62 mm. It is a sealing component used within the Broag Commercial boiler spare parts range, where it forms a compression seal at a mating joint to prevent water or gas leakage. O-rings of this type are consumable items and are typically renewed whenever the joint they sit in is disturbed.

• Visible water weeping or a damp trace around the joint the O-ring seals
• The O-ring is cracked, split or perished on inspection
• The rubber has hardened or taken a permanent flat set, so it no longer springs back
• Discolouration, scale or corrosion staining on or around the seal
• The seal has been disturbed during servicing and cannot be reused

• Confirm your appliance model against the manufacturer's parts list before ordering
• Check the required O-ring dimensions against the one being removed
• Inspect the mating faces for scoring or corrosion, as a damaged face will not seal even with a new O-ring
• Confirm how many O-rings the joint requires, as some assemblies use more than one
