High-Strength Retaining Compound 638, Green, 10 ml, Bottle

For a retaining compound offering high strength on all metals, including passive substrates, try LOCTITE® 638. You can expect high temperature performance and good oil tolerance, a fixture time of just four minutes, and a gap fill of 0.15 mm to 0.25 mm (0.006" to 0.01"). It even tolerates minor surface contaminants, including industrial oils. A high viscosity product, it’s ideal for shafts, gears, pulleys, and similar cylindrical parts, and can also be used for high-strength thread locking and thread sealing applications. Operating temperature is -55 °C to 180 °C (-65 °F to 355 °F). LOCTITE 638 meets the performance requirements of KIWA GASTEC QA AR 214 for admixtures up to and including 100% hydrogen gas on metal threaded fittings – certifications are available in select countries.
