HK Metalcraft gaskets are designed to keep gases and fluids under pressure from leaking.
Gaskets are manufactured from Steel, annealed to a hardness of 120 Knoop maximum, and from Copper, annealed to a hardness of 70 Knoop maximum, to enhance their sealing ability. Gaskets are available for over-the-thread, screw-on, stake-on, and pre-assembly (captive) applications. Our method of manufacturing and annealing of gaskets has solved engineering problems for the following applications by replacing rubber, fiber, aluminum, asbestos, and other types of gaskets.
Front Wheel Drives
Oil Drain Plugs
There are many other applications for our gaskets.
