What it is

This is a sealing gasket manufactured by Main for the joint between the burner connector or manifold and the injector rail. It forms a gas-tight seal at that connection on Main Multipoint water heaters. The gasket is a service part and should be renewed whenever the joint is disturbed.

Signs this part needs replacing

  • A smell of gas or a detected leak at the burner connector or manifold joint
  • Visible cracking, splitting or flattening of the gasket
  • The gasket has hardened or become brittle with heat cycling
  • The joint has been dismantled for servicing or repair and the old gasket cannot be reused
  • Soot staining or discolouration around the joint suggesting an incomplete seal

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check whether the joint is being opened for a service or a repair, as the gasket should be renewed each time
  • Verify the quantity required, as more than one joint of this type may be present
  • Isolate the gas supply and follow the manufacturer's instructions before any work on the burner assembly
