Permatex® PermaShield™ Fuel Resistant Gasket Dressing & Flange Sealant

Permatex® PermaShield™ Fuel Resistant Gasket Dressing & Flange Sealant

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°F (-50° to 260°C), this compound resists common engine fluids, including oil, gasoline, ethanol, water and anti-freeze and prevents contamination from moisture and dust.
