About the Tadpole Gasket Design:
Unlike conventional round stove rope gasket, a tadpole gasket combines a compressible sealing bulb with a flat mounting tail. On this gasket, the rounded 1/2" bulb provides the primary sealing surface while the 1" flat fiberglass tail provides the mounting area. Together, the profile measures approximately 1-1/2" overall. Using the correct profile is important because a standard round rope gasket may not provide the same fit, mounting surface, or sealing characteristics.

Replaces Empire / White Mountain Hearth Part Number 2025.3:
The R12136 tadpole gasket also replaces or cross-references the previous 2025.3 gasket. If your owner's manual, parts diagram, or existing gasket information calls for part number 2025.3, use R12136 as the current replacement reference.

Fitment Note:
Empire and White Mountain Hearth manufacture many different stove and fireplace models that may use different gasket sizes and profiles. Always verify the R12136 or 2025.3 part number in your owner's manual or parts diagram before ordering. If replacing an unidentified gasket, carefully compare the profile and measurements of your existing gasket with the dimensions listed above.

When Should a Tadpole Gasket Be Replaced?
High-temperature stove and fireplace gaskets naturally wear from heat exposure, compression, and normal appliance use. Replacement should be considered when the existing gasket becomes excessively flattened, frayed, torn, hardened, loose, separated from its mounting surface, or no longer creates the intended seal. Installing the correct replacement gasket can help restore the component to its designed sealing condition.

Installation Tips:
• Allow the stove or fireplace to cool completely before beginning installation
• Carefully remove the existing gasket and note its original position and orientation
• Take photos of the original gasket before removal if needed for installation reference
• Remove old gasket material, loose fibers, adhesive residue, dirt, and debris from the mounting surface
• Make sure the mounting surface is clean and dry before installing the replacement gasket
• Test-fit the gasket and confirm the correct orientation before removing the PSA backing
• Remove the adhesive backing gradually while pressing the flat tail firmly into position
• Do not stretch the gasket during installation, as stretching can affect the final dimensions and sealing performance
• Position the bulb in the same orientation as the original gasket
• Trim excess gasket only after confirming the required finished length
• Refer to your Empire or White Mountain Hearth owner's manual or service documentation for model-specific installation requirements
