Carbone 4858K503 Rupture Disc 1-1/2in 40 PSIG Series 3

The Carbone Lorraine 4858K503 Rupture Disc is a graphite, monobloc pressure-relief disk engineered for medium‑pressure service in process piping. Sized at 1-1/2 in nominal diameter, it belongs to the Series 3 family from Carbone Lorraine (now Mersen), a line that supports active diameters from 1 to 24 in and burst pressures ranging from 0.08 barg to 40 barg. This model is rated for a burst pressure of 40 psig, providing a predictable vent when the system exceeds the set point. Crafted in graphite with a monobloc design, it offers a simple, one-piece rupture element that delivers reliable performance in corrosive or high-purity environments and contributes to clean venting. Typical applications include chemical processing, petrochemical and refining systems, and other industrial process lines that require dependable overpressure protection to safeguard vessels and downstream equipment.
