Simply enter the total number of feet you need in the quantity box when ordering. For example, if your project requires 7 feet of gasket, enter a quantity of 7. You will receive approximately 7 continuous feet whenever possible. If you are replacing gasket material on multiple doors, glass panels, access panels, or sealing surfaces, measure all required gasket paths and add the measurements together before determining your order quantity. We recommend allowing a small amount of additional material for trimming and final fitting. What Is a Tadpole Gasket? Unlike conventional round rope gasket or flat fiberglass tape, a tadpole gasket combines a compressible sealing bulb with a flat mounting tail. The rounded bulb provides the primary compression and sealing surface, while the flat portion provides a convenient mounting area. This Total Hearth gasket features an approximately 1/2" diameter bulb and 1-1/4" overall width, making it suitable for compatible applications where both controlled compression and a flat mounting surface are required. Using the correct gasket profile is important. A standard round rope gasket, flat fiberglass tape, or tadpole gasket with different dimensions may not provide the same compression, mounting position, or sealing characteristics. High-Temperature Graphite Fiberglass Construction: This tadpole gasket is manufactured from woven fiberglass with a graphite treatment and has a service rating up to 1,000°F (538°C). Fiberglass provides an excellent combination of heat resistance, flexibility, and durability for compatible high-temperature sealing applications. The material is non-asbestos, will not absorb water, and does not attract mold or mildew. The woven construction is also designed to minimize excessive fraying and unraveling when properly measured and cut. PSA Self-Adhesive Backing: The flat portion of the gasket features a pressure-sensitive adhesive (PSA) backing that helps hold the gasket in position during installation. This makes it easier to maintain proper gasket alignment while working around compatible doors, glass panels, access panels, and other sealing surfaces. For best adhesion, remove old gasket material, adhesive residue, soot, grease, dirt, and debris before installation. The mounting surface should be clean and completely dry before applying the PSA-backed gasket. The PSA backing is primarily designed to assist with positioning and installation. Always follow the equipment manufacturer's recommendations regarding additional adhesive, retainers, fasteners, glass hardware, or other securing methods. Common Applications: • Wood stove gasket applications • Pellet stove gasket applications • Gas stove gasket applications • Fireplace gasket applications • Fireplace glass seals • Stove and fireplace door seals • Glass panel gasket applications • Access doors and cleanout covers • Service and inspection panels • Heating appliance sealing surfaces • Other compatible high-temperature applications requiring a 1/2" bulb x 1-1/4" overall tadpole gasket Fitment Note: This is a generic replacement tadpole gasket and is not sold for one specific appliance brand or model. Before ordering, compare your existing gasket or application requirements with the specifications provided in this listing. Verify the gasket profile, approximately 1/2" bulb diameter, 1-1/4" overall width, graphite fiberglass construction, PSA backing, mounting method, and required length. Dimensions alone should not be used as the only method of determining compatibility. If your appliance manufacturer specifies a particular OEM gasket, compare all available specifications with this gasket before using it as a replacement. When Should a Tadpole Gasket Be Replaced? High-temperature gaskets are exposed to repeated heating, cooling, compression, and normal wear. Over time, fiberglass gasket material can become flattened, frayed, torn, hardened, loose, excessively compressed, or separated from the mounting surface. Replacement should be considered when the existing gasket is visibly damaged, has lost its original profile, or no longer provides the proper seal for the application. Installation Tips: • Allow the appliance or equipment to cool completely before beginning installation • Carefully inspect the position and orientation of the existing gasket before removal • Take photos of the original gasket installation if needed for reference • Remove the old gasket and any loose fiberglass material • Remove old adhesive, soot, grease, dirt, and debris from the mounting surface • Make sure the mounting surface is clean and completely dry • Compare the replacement gasket profile and dimensions with the original before installation • Test-fit the gasket before removing the PSA protective backing • Confirm the proper orientation of the bulb and flat mounting section • Remove the adhesive backing gradually while pressing the gasket evenly into position • Do not stretch the fiberglass gasket during installation • Work gradually around curves and corners to maintain a consistent gasket profile • Trim excess gasket only after confirming the final required length • Follow the appliance or equipment manufacturer's installation procedures when available Why Choose Total Hearth Tadpole Gasket?
