The Kramp LC1300829 Flexible Gasket Maker 5188 is a high-performance 50ml anaerobic sealant designed for robust sealing of close-fitting, rigid metal flanges. This red methacrylate-based compound cures in the absence of air between metal surfaces, forming a flexible, solvent-resistant seal that prevents tearing or degradation. It is effective on both active metals like brass and copper, and passive metals such as stainless steel. With a temperature resistance from -55 °C to +150 °C and excellent resistance to oil and glycol, it ensures reliable performance in demanding applications. It has a fixture time of 20 minutes and achieves full cure in 24 hours, with a gap filling capacity of 0.5 mm.
