Oseco FAS Forward Acting Rupture Disc

High-performance rupture disc for liquid or gas applications

The Oseco FAS™ (Forward Acting Scored) rupture disc is a high-performance forward acting rupture disc designed and manufactured for high-performance and demanding rupture disc applications.

The FAS™ is scored after the forming of its high crown. This process yields a high-performance disc to withstand the most difficult applications. The FAS™ offers a smooth non-scored surface toward the process media. This limits product accumulation on the disc and reduces the risk of polymerization and crystallization of media on the disc surface.

Offering the lowest Lowest Flow Resistance Factors (FRF) and Kr values for gas and liquid in the market and a high combination capacity factor, the FAS™ is an excellent choice for isolating safety relief valves.

The Oseco FAS™ disc is manufactured at Oseco’s manufacturing facility in Broken Arrow, Oklahoma, USA.
