This welding insulator gasket is a great ADDITION to my toolbox... Its design is perfect for automotive welding applications. Thanks to my knowledge gained in practice, I can say that this product is easy to install and provides superior insulation to prevent the torch from overheating during the welding process. I appreciate the quality of the materials used which ensure durability and longevity. The only downside is that it can be a bit pricey compared to other similar products on the market. Overall I highly recommend it..
