RD500 ATLAS® High Performance Rupture Disc

RD500 ATLAS® High Performance Rupture Disc

Higher Pressure, High Performance

ATLAS offers higher pressure capability, while still featuring high performance benefits including a 95% operating ratio, liquid or vapor service, back pressure resistance and unrivaled cycling capability. Higher burst pressures of up to 1500 PSIG (103.42 BARG), makes ATLAS the endurance workhorse of the G2 Technology line of products.
