VATSEALs are a metal seals for vacuum and cryogenic applications. Metal seals are used instead of elastomer seals if - permeation through an elastomer seal is not acceptable, - outgassing must be very low, - temperature exceeds 200°C, - process gases are not compatible with elastomer seals, - high radiation resistance is required.
