This anaerobic adhesive is formulated for bonding cylindrical parts with narrow gaps, curing in the absence of air. It effectively prevents loosening and leakage from shock and vibration, adheres to both active and passive metals, and demonstrates high temperature resistance and good oil tolerance, even with minor surface contaminants.This anaerobic adhesive is formulated for b

Overview
Loctite® 638 is designed for the bonding of cylindrical fitting parts, particularly with narrow bond gaps approaching 0.25 millimeters. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high temperature performance and good oil tolerance and tolerates minor surface contaminants.
Features & Benefits
Tolerates minor contaminants, including industrial oils
High strength on all metals, including passive substrates (e.g. stainless steel)
High temperature resistance
Ideal for shafts, gears, pulleys and similar cylindrical parts
