Composite Flat Seat Rupture Disc

A versatile line of high-performance, corrosion-resistant rupture discs, our composite discs are ideal for systems that require lower burst pressures than standard discs can provide. Our composite rupture disks consist of two or more metallic or non-metallic components. The components typically consist of a metallic top section and a metallic or non-metallic seal with optional vacuum support, protective rings, gaskets or outlet liner. This rupture disc features a flat seat design for superior metal-to-metal sealing. If you're looking for a 30° angular “light lip” seat, ideal for normal operating pressures, try our Standard 30˚ seat rupture disk.
