Ultra Red Gasket Maker 3.35 oz Carded Tube

PERMATEX Ultra Red Gasket Maker in a 3.35 oz carded tube is a silicone-based anaerobic sealant engineered for engine assembly and automotive fluid containment. This sensor-safe formulation meets the demands of mechanics, restoration specialists, and technical professionals who require dependable gasket sealing without compromising oxygen sensor integrity or electronic fuel injection systems. The ultra red color provides high visibility during application and inspection, eliminating doubt about seal coverage on critical engine surfaces.

The 3.35 oz tube delivers controlled dispensing for precision gasket work on valve covers, oil pans, timing covers, and transmission housings. Ultra Red cures to form a flexible, durable seal that resists engine heat, oil exposure, and vibration—core requirements for sustained engine performance. The sensor-safe chemistry means technicians can confidently use this product on late-model vehicles equipped with oxygen sensors and catalytic converters without risk of sensor fouling or performance degradation. Curing time and temperature resistance are consistent with industry-standard anaerobic sealants, making this a reliable choice for both original equipment and aftermarket gasket applications.

Automotive technicians, engine rebuilders, and DIY enthusiasts working on gasket replacement or engine reassembly will find this tube format convenient for moderate-volume work. The carded packaging protects the tube and provides a professional, organized appearance on shelves or in service vehicles. Whether sealing a single engine block or managing multiple repair bays, the 3.35 oz size balances usable content with waste minimization, making it practical for shops that cycle through fasteners, gaskets, and sealants regularly.
