Burst Disc / Rupture Disc

UPC designs high precision, critical application burst discs “rupture disc / rupture diaphragm” with highly proficient and experienced engineering as our benchmark. Designed to specific customer requirements as well as industry standards, we understand how to turn pressure safety needs into product reality. Knowledge and attention to the manufacturing processes and technical issues is the heart of UPC's engineering integration. The ability to reduce the design cycle and cost of qualified hardware makes UPC a preferred supplier. Wherever there exists the need for high precision pressure relief to protect people, payloads, delicate equipment or systems, UPC delivers the best performance available. We provide both custom-engineered and standardized solutions to suit the requirements from “once a generation” space projects to needs in production industrial, commercial aerospace, and transportation solutions.
