LOCTITE 648 is designed for the bonding of cylindrical fitting parts. 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 exhibits a robust curing performance. The product also works on passive substrates and offers high-temperature performance and good oil tolerance. Prevents loosening: It fills all gaps between the cylindrical components and cures into a hard thermoset plastic. This unitizes the assembly and prevents loosening and leakage from shock and vibration. Works on all metal substrates. Tolerant towards minor surface contaminations. Proven to be tolerant of minor contamination due to industrial oils. High strength on all metals, including passive substrates (e.g. stainless steel).
