Permatex 85420 Gasket Dressing Sealant, 2 oz Tube, Liquid, Ketone Blue

Specially formulated for superior fluid resistance, this polyester urethane-based gasketing compound withstands extreme temperature changes without hardening. Its non-setting, non-hardening character remains tacky even with rapid changes in temperature, enabling repeated assembly and disassembly of parts. Suitable as either a gasket maker or dressing, PermaShield™ seals surface imperfections between metal parts and is ideal in high-performance applications. With an operating temperature range of -60 to 500 deg F, this compound resists common engine fluids, including oil, gasoline, ethanol, water and anti-freeze and prevents contamination from moisture and dust.
