FSSCDS - Sanitary Rupture Discs

FSSCDS - Sanitary Rupture Discs

The FSSCDS Sanitary Rupture Disc is a compression-loaded, micro-scored disc that opens in petal form with four, six, or more radial score lines to provide fast, reliable pressure relief. Designed to meet the strict hygiene requirements of 3-A SSI, it is ideal for use in the pharmaceutical, food, and biotechnology industries, where product purity and cleanability are critical. The disc is manufactured entirely from AISI 316L stainless steel (with alternative alloys available on request) and features a smooth process-side surface, making it fully compatible with CIP and SIP cleaning processes for maintaining aseptic conditions.

Installation is simplified using FDA and USP Class VI approved PTFE gaskets, compliant with 3-A and EU 10/2011 standards, allowing easy integration into sanitary clamp connections such as Tri-Clamp and Tank Connection fittings. The disc activates within milliseconds under overpressure, opens cleanly without fragmentation, and in many applications can operate under full vacuum without additional supports. It also offers excellent corrosion resistance and optional linings for enhanced chemical protection.
