LOCTITE® SF 7414 is a blue, high-viscosity, solvent-based paste for service personnel or inspectors to quickly detect any adjustments or tampering with equipment. It is developed for use on compression fittings, studs, nuts, parts and assemblies after they’ve been set to the correct torque, tension or position, thus providing an inexpensive method for warranty protection. It dries quickly and provides excellent adhesion to metals, including aluminium, magnesium, titanium, stainless steel and copper.
