Powerbead Clear RTV Silicone 7.25oz

Powerbead Clear RTV Silicone 7.25oz is the go-to gasket sealant for serious vehicle builders, mechanics, and enthusiasts who demand reliable performance on critical engine and transmission sealing jobs. Whether you're rebuilding a small-block V8, sealing a pan gasket on a vintage rebuild, or protecting custom fabrication work, this clear RTV formula delivers consistent results across a wide range of automotive applications. The 7.25oz tube size offers practical coverage for single-job applications without waste, making it ideal for both professional shop environments and home garage builds.

This clear silicone RTV cures to form a flexible, durable gasket that resists oil, coolant, and fuel exposure—critical properties when sealing engine blocks, valve covers, oil pans, and transmission housings. The non-slump formula maintains its position during application, preventing runs and drips on vertical or overhead surfaces, which is essential when working on mounted engines or complex builds. PERMATEX's proven silicone chemistry ensures consistent adhesion to metal, cast iron, and aluminum surfaces while remaining removable for future service intervals—a significant advantage over permanent adhesives when modification or repairs are inevitable.

Mechanics and fabricators routinely specify Powerbead Clear RTV for engine block work, transmission pan sealing, timing cover applications, and custom manifold installations where visual inspection and surface cleanliness matter. The clear formula allows you to monitor cure progress and verify complete coverage without guesswork. Compatibility spans gasoline engines, diesel platforms, and transmission systems; cure time typically reaches handling strength in 1–2 hours and full strength within 24 hours, fitting standard shop turnaround timelines.
