What it is

The RGN120 is a flange gasket supplied under the Oil Spares brand, listed under the model reference Oil Spares - Giersch. It is a sealing component sized to sit between two mating flange faces and close the joint against leakage on a boiler or associated heating system pipework. The catalogue description for this item carries an ordering check, so the reference must be confirmed against the system before an order is placed.

Before you order

  • Confirm the gasket reference RGN120 matches the joint requiring the seal, as the catalogue entry flags an ordering check.
  • Check the flange size and joint arrangement on the appliance against the manufacturer's documentation for the Giersch boiler range.
  • Verify the 10 B 4 reference noted in the product description against the boiler or system parts list before committing to the order.
  • Have the appliance model and the existing gasket reference to hand so the correct item can be matched.
