Permabond® HL138 Anaerobic Retaining Compound, 250ML Bottle

Permabond® HL138 is a single-component liquid adhesive that cures only when it is in contact with metal and oxygen is excluded. It fills the air space between mating parts, and once cured, it eliminates wear, erosion, and pitting. The cured adhesive forms a tough, cross-linked plastic with excellent environmental and temperature resistance.

Because HL138 fills the gap between parts, shaft-and-hub assemblies can be made with a clearance fit instead of an expensive press fit, while push-out force actually increases. It develops full strength quickly on a variety of metals, making it well suited to high-speed production lines.
