DISS GASKETS
DISS GASKETS
As a vendor of DISS Gaskets for the past 25 years, Critical Systems inspects each gasket under magnification to assure proper fit and functionality. The DSS-1000-N is the premier gasket used for sealing UHP CGA (DISS) gas cylinder connections. Designed for demanding purity performance, the robust and non-rotating connection is built to specification for the microelectronics industry. Our proprietary annealing process ensures a leak-free installation, and eliminates torrid wear issues. The DSS-1000-N is the gasket of choice whenever high purity gases call for leak free connections.

Key Improvements in CSI’s DISS Gaskets
Dead Soft Annealing Process
CSI’s DISS Gaskets, made from Nickel 200 or Stainless Steel, undergo a proprietary annealing process that results in a “dead soft” material for secure metal-to-metal sealing. Carefully controlled temperature, soaking time, and cooling stabilize the metal’s structure, ensuring a highly durable, leak-proof seal.
Electropolished Surface
Electropolishing on CSI’s DISS Gaskets creates a smooth, corrosion-resistant finish, improving seal integrity. This process removes contaminants, enhances chromium-to-iron ratios, and forms a robust oxide layer, minimizing potential corrosion sites and enhancing long-term durability.
Rigorous Inspection Standards
CSI’s ISO 9001-certified inspection process ensures zero-defect DISS Gaskets, backed by thorough vendor quality control. Standardized protocols, detailed documentation, and continuous improvement initiatives drive reliability and product excellence, ensuring that each gasket meets exacting industry standards.
23 Years Without a Failure!
CSI’s DISS Gasket design has stood the test of time, offering unparalleled reliability and durability in sealing specialty gas cylinders to ultra-high purity (UHP) pigtails. With nearly 25 years of zero failures, our proprietary improvements make CSI’s DISS Gaskets the industry’s most trusted solution.
