Simple All-Metal Sealing for UHV, XHV, UHP
The Atlas All-Seal simplifies UHV, XHV, & UHP demountable sealing, enabling smaller, lighter no/low permeation seals. All-Seal gaskets can be applied in many geometries enabling better performance.
All-Seal for Ultra High Purity
Elastomeric seals are sources of contamination. Contaminants are added to elastomers to reduce their inherent permeation, which for many applications becomes a trade-off between permeation and contamination. Atlas All-Seal gaskets are metallic and are considerably cleaner and do not compromise on permeation. They are typically aluminum but are available in other metallic materials (nickel, copper, tin, etc.). Consequently, alternative alloys of All-Seal gaskets can be selected to improve chemical resistance.
Versatile All-Metal Gaskets
The All-Seal gasket combines the low permeation of metallic seals with the versatility of O-rings.
All-Seal for Nuclear and Radiation Applications
Atlas aluminum All-Seal gaskets have a low Z and do not cross-link like elastomeric seals. Consequently they have a low nuclear activation and retain the seal longer than elastomeric O-rings.
All-Seal for Existing Chambers
Atlas All-Seal gaskets enable low and high vacuum chambers that have previously been designed to seal with elastomeric and fluoroelastomers (such as viton, FMK, buna, PTFE, kalrez and Chemrez, teflon, etc.) to be retro-fitted for ultra high vacuum.
