Permatex 27036 Optimum Grey Gasket Maker is a premium RTV silicone sealant engineered for high-torque and vibration-prone automotive applications. The OEM-style grey formulation provides excellent resistance to oils, shop fluids, and thermal cycling while maintaining gasket integrity under heavy clamping loads. Its low-odor, sensor-safe formula makes it suitable for modern engine and drivetrain systems. || Designed for valve covers, timing covers, intake manifolds, water pumps, thermostat housings, and transmission pans, Optimum Grey delivers superior adhesion and flexibility compared to conventional RTV sealants. The formulation withstands repeated expansion and contraction while maintaining a durable leak-resistant seal. || The 3.35-ounce tube offers convenient application for repairs and maintenance projects. Its high-torque performance characteristics make it especially well suited for import and domestic engines where OEM specifications call for grey RTV gasket material.
