Permatex 25229 The Right Stuff Black 1-Minute Gasket Maker is a formed-in-place elastomeric gasket sealant for non-fuel sealing applications on heavy-duty trucks and commercial equipment. The black formula provides higher oil resistance and greater flexibility compared to the Right Stuff Grey version. Continuous temperature range is -75F to 450F (-59C to 232C), with intermittent service to 500F (260C). The sealant resists automatic transmission fluid, coolant, engine oil, and common shop fluids, and is rated sensor-safe. One tube covers enough surface area to replace two or three large cut gaskets. Call us to confirm proper fit or application for your equipment.
