Nu-Calgon 4289-04 Flange Sealant 50ml Tube


NuLock formulation 4289-04 is a flange sealant designed to aid in sealing in small gap fill areas of 0.01 inch (0.25mm) or smaller on rigid metal faces and flanges. The product provides an elastic seal aid if concern exists about minor leakage at the flange. Examples include a poor mating contact across the gasket or an imperfection in the metal seal surface. In other applications, a gasket taking a set results loss in bolt load on the gasket surface, which could result in leakage from the system. Using NuLock in this application can aid seal durability of this flange connection. In other specialized applications, NuLock provides a form-in-place gasket option between small gap (0.01 inch) metal-flanged parts. The product has a low strength cure; the flange is easily removal as necessary. NuLock is NOT for use on plastic parts or for oxygen-rich systems or as a sealant for strong oxidizing materials. Temperature range is -65°F to 300°F. Product has excellent chemical resistance. Handling time is 10+ minutes, functional cure 3-6 hours and full cure is 24 hours.
