ST-3 is a pre-applied process whereby a series of resilient thread sealants are coated onto straight or tapered threaded fasteners. A widely-used automotive industry approved process, ST-3 creates a custom-fit elastic gasket around fastener threads which prevents the passage of most fuels and chemicals, and helps keep joints tight under severe vibration.
OVERVIEW
HOW IT WORKS
During the ST-3 pre-application process, ND Industries accurately dispenses a get range of materials onto fasteners, making them self-sealing. The applied sealants act as a partial lubricant, reducing torque tension variation and preventing the galling of metals. they’re going to not harden or cure, allowing fasteners to be adjusted, removed, and replaced, throughout the lifetime of the part if needed. Processed fasteners arrive to the customer dry to the touch, and prepared for immediate assembly.
