The Ruelco fuse plug is a heat sensitive device designed to vent control pressure at a predetermined temperature. Ruelco fuse plugs are manufactured using a process that assures a leak free operation. The sensing temperature of the fusible material is clearly marked on each fuse plug to assure proper identification.
