An original gasket maker formulated for heavy duty applications. It forms reliable “formed-in-place” gaskets that resist cracking, shrinking and migration caused by thermal cycling. Ideal to replace almost any cut gasket and can be used to coat pre-cut gaskets to increase reliability. It is permanently flexible and stable at temperatures between -80 °F to 500 °F (-62 °C to 260 °C) intermittent. It is also highly resistant to automotive fluids.
