Lavametal R technology for cylindrical assemblies. Replacing worn cylindrical assemblies or keyed parts is costly. Re-machining usually involves expensive downtime. And no maintenance engineer wants that to happen! Not attending to loose or worn components can result in a complete breakdown. Using Lavametal R anaerobic liquids and pastes ensures 100% contact between the mating surfaces of loose parts. They work by becoming hard due to the absence of air and metal contact.
