Product Description

This is a genuine replacement door gasket kit for several models of RSF wood burning fireplaces.  This RSF Energy Gasket Kit ships new in its original packaging, it is not an aftermarket equivalent.

RSF Part Number: FO-FDGRK1 (has now been replaced with FO-GRK8 in 2023)

Wood Fireplace Gasket Rope Description:

  • Gasket: 5/8″ x 90″ long
  • Includes Gasket Glue

Applicable Models: 

  • RSF Energy Onyx wood fireplace
  • RSF Onyx 2 wood fireplace


The door gasket is a barrier between the doors and the face of the fireplace.  When the gasket starts to wear out, the unit will leak air and cause the fireplace to over fire which may lead to damage.

Installation Tips

Please ensure that you remove all debris from the gasket channel by using a wire brush or something else.  Its a cast iron door, you so can’t hurt it.  Drop a think bead of glue (not too much) to ensure gasket does not get hard.  Ensure ends are close together.

Note: Wood stove and fireplace door gaskets are also commonly referred to as “Door Sealers” (Asbestos style rope that goes around the door channel).
