What it is

The Broag gasket S100056 is a flat sealing gasket measuring 27mm outside diameter, 20mm inside diameter and 2.5mm thick. It is used on Broag Commercial gas boilers, including the GAS 210 ECO PRO Premix Boiler, to seal a joint against leakage. Supplied in a pack of five.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket
  • Weeping or dripping at the joint the gasket seals
  • Water or gas traces around the sealing face
  • Gasket stuck to the mating surface or breaking up on removal
  • Recurring leaks after the joint has been tightened

Before you order

  • Confirm the gasket dimensions (27mm O/D, 20mm I/D, 2.5mm) match the one removed
  • Check the boiler model against the fit list above
  • Inspect the mating surfaces for corrosion or pitting before fitting
  • Note the pack contains five gaskets
