Product Description

Loctite 638 Maximum Strength Retaining Compound 250ml is a high strength retaining compound ideal for applications experiencing high dynamic forces or cyclic loading.

  • Locks cylindrical assemblies with up to 0.25mm diametrical clearance
  • Provides the best resistance to dynamic, axial and radial loads from moving parts
  • Recommended for retaining shafts, gears, pulleys and similar cylindrical parts in demanding applications

NSF registered (Reg. No. 123010), Loctite 638 forms a durable, high strength bond between metal surfaces, replacing the need for expensive replacement parts or additional fastening methods. It cures in just 5 minutes at room temperature on steel, with a temperature resistance up to 150°C.

Ideal use cases include retaining components in machinery experiencing vibration, such as industrial motors, pumps and compressors. The high strength bond also makes it suitable for automotive applications with rotating or reciprocating engine parts.
