The Tuthill Melt Plug 92331 is a safety-device plug specifically engineered for dry bulk trailer blower systems and pneumatic conveyance applications. Its fusible element is calibrated to melt at about 390 °F (≈ 199 °C) if overheating occurs, thereby relieving pressure or signaling a fault condition. Ideal for tanker/trailer blower assemblies, this plug helps protect equipment and cargo during excess-heat events. It features a standardized 1/2-inch thread size and is constructed from durable materials suitable for heavy-duty use.
