What it is

The pilot gasket, part number 1000-1500850, is a sealing component manufactured by Johnson & Starley for the pilot assembly on its Hispec J25RS warm air unit. It seals the pilot gas connection, preventing leakage at the joint. It is classed as an O-ring, washer and gasket item within the boiler spares range.

Signs this part needs replacing

  • Visible perishing, cracking or hardening of the gasket material
  • Signs of gas leakage or a smell of gas at the pilot assembly joint
  • Soot staining or discolouration around the pilot connection
  • The gasket is flattened, deformed or missing when the pilot assembly is inspected
  • The pilot fails to hold a stable flame after servicing the pilot assembly

Before you order

  • Confirm the appliance model is a Johnson & Starley Hispec J25RS
  • Check the existing gasket against the pilot assembly joint before removal
  • Verify the part number 1000-1500850 matches the one on the existing component
  • Gas-carrying work must be carried out by a competent, registered engineer
