The Ashcroft 45-1259SD-02L pressure gauge, also referenced as 451259SD02L, is a 4.5-inch dial instrument with a 1/4 NPT lower mount connection for direct installation in process piping. Its solid-front stainless steel case and socket design suit severe service environments that require protection against overpressure or corrosive media. The gauge supports accurate pressure monitoring in oil and gas, chemical, and power plant systems where the 1259SD series construction provides the needed durability.
