What it is

A spring ring washer sized A4.3, supplied by Broag as a spare part for Broag Commercial gas boiler appliances. The washer fits the GAS 320 ACE and GAS 620 ACE ranges and is used to maintain tension on the fastener it sits beneath. It is supplied in a pack of 10 pieces.

Signs this part needs replacing

  • The washer is visibly corroded, pitted or cracked.
  • The spring section has flattened, so it no longer holds tension on the fastener.
  • The washer has deformed or gone out of shape where it seats.
  • A washer is missing from a fastener that was disturbed during service work.

Before you order

  • Confirm the appliance model and variant against the fit list above.
  • Check the existing washer size designation to ensure A4.3 matches the fastener.
  • Confirm the washer type is a spring ring rather than a plain or serrated washer.
  • Consider how many fasteners you intend to rebuild, as the pack contains 10 pieces.
