Head Gasket

DNJ Head Gasket

DNJ® Cylinder Head Gaskets are engineered to form a critical seal between the engine block and cylinder head, ensuring maximum compression and preventing leaks of coolant, oil, and combustion gases. Manufactured to meet or exceed OEM quality standards, these gaskets are built for optimal engine performance, efficiency, and durability.

DNJ® Cylinder Head Gaskets are crafted from advanced multi-layer stainless steel (MLS) construction for modern engines, or premium composite materials for older applications. The multi-layer steel design incorporates embossed sealing beads and elastomer coatings such as Viton or nitrile for superior micro-sealing and resistance to oil, coolant, and extreme temperatures. Additional materials like aramid fiber and graphite are chosen for their exceptional tensile strength, thermal stability, and ability to conform to cylinder head and block imperfections. These materials are meticulously selected to ensure each gasket performs reliably under the intense conditions of modern engines.

DNJ® proudly offers the largest inventory of MLS cylinder head gaskets in the industry, ensuring coverage for a wide range of domestic and import vehicles. To complement its sealing technology, and to complete the job, DNJ® also offers a complete line of Head Bolts, which is critical for proper cylinder head installation. It is important to note that Torque-To-Yield (TTY) head bolts must never be reused, as reinstallation can compromise clamping force and lead to engine failure. With precision engineering and top-tier materials, DNJ® Cylinder Head Gaskets deliver exceptional performance and long-lasting durability.
