LOCTITE 638 – High-strength, general purpose bonding of cylindrical parts

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 gap fill of 0.15 mm to 0.25 mm (0.006" to 0.01").

A high-viscosity product, it’s ideal for shafts, gears, pulleys and similar cylindrical parts, and can also be used for high-strength threadlocking 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.

A 1-part, designed for bonding cylindrical fitting parts, particularly with narrow bond gaps up to 0.25 mm (0.01"). Great for a fast cure on all metals, including passive substrates like stainless steel.
