This Generac insulator gasket is for Generac brand generators. It is used to keep heat from the engine away from the carburetor. The longer the generator runs, the warmer it will get, and a properly functioning Generac insulator will prevent the device from overheating. After use and with normal wear and tear, these Generac insulator gaskets will begin to wear down and become ineffective. Users will notice the generator is getting too warm after running for some time, or the entire device may fail. A worn down or damaged insulator gasket must be replaced before continuing operations of the generator.Replacing a Generac insulator gasket can be done relatively quickly with the proper tools. Always wear protective gloves when repairing any engine components. Remove the old or ineffective gasket before replacing it with a new one. Ensure all parts are lined up and secure before starting the machine.This Generac insulator gasket is an authentic OEM replacement part. It is sold as an individual unit. The insulator gasket is for Generac brand generators only, and it fits several different models. The replacement part is made of high-quality, durable materials.
