Since 1997, BlueDevil Products has been providing quality sealants, cleaners, and other automotive fluids to the aftermarket industry. Whether you have a blown head gasket, leaks in power steering, or a cracked cylinder head, in the company's product line, you're sure to find the right sealer to stop leaks permanently. These sealers are easy-to-use, affordable alternatives to time-consuming and costly repairs. They're also safe to use, being free from solid or particulate matter that could clog or damage the system.

The BlueDevil head gasket sealer is a mainstay in the company's product range. It is formulated to permanently repair leaks in blown head gaskets, warped cylinder heads, freeze plugs, and heater cores. This sealer safely works in both gasoline and diesel engines and bonds to metal surfaces including aluminum, cast, and alloy ones as well as plastic. It is an efficient solution that will save you time and money on repairs. To stop leaks in the engine cooling system, there is the BlueDevil radiator and block sealer. Its formulation was proven to meet ASTM D6107, D3147, and D1181 specifications, which means it's an effective stop-leak additive that does not affect heat transfer properties and fluid flow.

Address transmission fluid leaks before they cause serious damage. The BlueDevil transmission sealer penetrates into worn-out, cracked, hard, and shrunken seals and restores their size and properties as you drive. Like other sealants, this one offers a permanent leak-stopping solution while being safe to use. If you need to repair leaks in other systems or do scheduled maintenance, there are the right Blue Devil automotive products for many kinds of work, including hydraulic system sealers, oil stop leak products, power steering fluids, radiator flush, and more.
