Fuse Plugs

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 ensure proper identification.

The Ruelco fuse plugs are available in 316 stainless steel with various sensing temperatures (158, 168, 183, 210, & 283 °F) and sizes (1/2", 3/8", and 1/4" MNPT).
