ND ST-3 is a tough, resilient thread sealant for fasteners with straight or tapered threads. A widely-used, Automative Approved product, ST-3 forms a custom-fitting, elastic gasket right in the threads, that prevents the passage of most fuels and chemicals, and helps keep joints tight (even under severe vibration). ST-3 is designed to instantly seal both tapered and straight threads against most fluids, fuels, and lubricants.
