An original gasket maker formulated for high temperature and 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 temperature of between -80 °F to 650 °F (-62 °C to 343 °C) intermittent. It is also highly resistant to automotive fluids.
