Simply enter the total number of feet you need in the quantity box. For example, if your application requires 7 feet of gasket, enter a quantity of 7. You will receive approximately 7 continuous feet of gasket whenever possible. If gasket material is required for multiple sections, measure each gasket path and add the measurements together before ordering. We recommend allowing a small amount of additional material for corners, trimming, and final fitting. About the Tadpole Gasket Design: Unlike conventional round rope gasket or flat gasket tape, a tadpole gasket combines a compressible bulb with a flat mounting tail. This specialized profile provides both a defined compression area and a convenient mounting surface. On this gasket, the approximately 1/2" bulb provides the primary compressible sealing surface, while the 7/8" flat fiberglass tail provides the mounting area. Together, the complete gasket profile measures approximately 1-3/8" overall. Using the correct gasket profile is important. A standard round rope gasket, flat tape gasket, or tadpole gasket with different dimensions may not provide the same compression, mounting position, or sealing characteristics. Graphite Fiberglass Construction: This gasket is manufactured from graphite-treated fiberglass for demanding high-temperature sealing applications. The woven fiberglass construction provides flexibility while allowing the bulb section to compress between compatible mating surfaces. The graphite treatment also gives the gasket its dark appearance and makes it well suited for applications where a durable, flexible high-temperature fiberglass sealing material is required. PSA Self-Adhesive Backing: The flat mounting section features a pressure-sensitive adhesive (PSA) backing designed to simplify positioning during installation. Remove the protective backing gradually and press the flat fiberglass tail firmly against the prepared mounting surface. The PSA is primarily designed to assist with gasket positioning. Always follow the equipment manufacturer's instructions regarding gasket installation and any additional fastening, adhesive, or sealing requirements. Common Applications: • High-temperature door seals • Glass and panel sealing applications • Heating appliance gaskets • Stove and fireplace sealing applications • Access doors and panels • Firebox sealing applications • Replacement for compatible bulb-and-tail gasket profiles • Other high-temperature applications requiring a 1/2" bulb x 7/8" flat tadpole gasket Fitment Note: This is a generic replacement tadpole gasket and is not manufactured for one specific brand or model. Before ordering, compare the gasket profile and dimensions with your existing gasket or the specifications required for your application. Confirm the 1/2" bulb diameter, 7/8" flat-tail width, approximately 1-3/8" overall width, PSA mounting configuration, and required length. Dimensions and gasket profile should be verified carefully before installation. How Much Tadpole Gasket Should I Order? Measure the complete gasket path where the replacement material will be installed. If you need gasket for multiple doors, panels, glass sections, or other surfaces, measure each section and add the measurements together. For example, if your application measures approximately 6.5 feet, ordering 7 or 8 feet provides additional material for final fitting and trimming. When Should a Tadpole Gasket Be Replaced? Repeated heating, cooling, compression, and normal use can eventually cause high-temperature fiberglass gasket material to deteriorate. Replacement should be considered when the existing gasket becomes excessively flattened, compressed, frayed, torn, hardened, loose, separated from its mounting surface, or no longer provides the intended seal. When replacing an existing gasket, compare the original profile and dimensions carefully before selecting a replacement. Installation Tips: • Make sure the appliance or equipment is completely cool before beginning installation • Carefully note the position and orientation of the original gasket before removal • Take photos of the existing gasket installation if needed for reference • Remove the old gasket and loose gasket material • Clean away old adhesive, fibers, dirt, grease, soot, and other residue • Make sure the mounting surface is clean and completely dry • Test-fit the new gasket before removing the PSA backing • Confirm the correct bulb orientation before installation • Remove the adhesive backing gradually while pressing the flat tail evenly into position • Avoid stretching the fiberglass gasket during installation • Work gradually around corners and curves to maintain a consistent gasket profile • Trim excess material only after confirming the final required length • Follow the equipment manufacturer's installation procedures whenever applicable Why Choose the Total Hearth Tadpole Gasket? The specialized combination of a 1/2" compressible bulb, 7/8" flat mounting tail, approximately 1-3/8" overall profile, graphite-treated fiberglass construction, and PSA self-adhesive backing makes this gasket a versatile replacement option for compatible high-temperature sealing applications. Because it is sold by the running foot, you can purchase the amount needed for your specific project rather than being limited to a predetermined length.
