As cooling system experts, MotoRad knows what is necessary to manufacture a high-quality part that will stand up to the rigors of today’s demanding cooling system environments where others fail. MotoRad offers an extensive line of adhesive backed thermostat gaskets and rubber seals to support thermostat installation. MotoRad's thermostat gaskets are made from high quality materials suitable for resistance to high temperatures and engine coolant to maintain a good seal. The adhesive backing also reduces installation time by ensuring proper alignment and ease of installation. MotoRad's thermostat seals are precision designed and made from high quality rubber products ensuring an accurate fit and durability for a long lasting seal.
