Description

Secure your cylindrical parts and shaft hub joints with the high-strength performance of LOCTITE 638. This anaerobic adhesive is designed for professional-grade applications where stability is required. It excels at bonding close-fitting metal surfaces, even when bond gaps approach 0.25 mm. Because it cures in the absence of air, it provides a reliable connection that prevents parts from loosening due to vibration or impact. This versatile metal adhesive is suitable for a wide range of materials, including both active metals and passive metals like stainless steel. It is built to withstand harsh environments, offering resistance to temperature fluctuations from -55C and maintaining integrity against oil. Whether you are working on gearboxes or securing sliding bushings in a housing, LOCTITE 638 helps prevent leaks and corrosion, ensuring your mechanical assemblies remain stable and secure.

Temperature and oil resistant performance effective in environments ranging from -55C.
