Deacon 770-L can be used as gasket dressing to improve the sealing capability of many gaskets. Deacon 770-L can also be applied to many types of gaskets (including spiral wound) to reseal them, thereby prolonging their useful life. Deacon 770-L can be used as the only sealant on low-tolerance metalto-metal joints. Deacon 770-L is brushed onto the sealing surface in a complete, uniform, thin coating. Note: Deacon 770-L will flow filling small voids, and surface irregularities creating a seal between the gasket and the flange surface where most leak problems initiate.
