Professional manufacturer and global supplier of UHP fittings for semiconductor and vacuum systems.
Metal gasket face seal fittings (VCR type) are ultra high purity connectors designed for leak-tight sealing in vacuum and high-purity gas systems.
They utilize a precision metal-to-metal sealing mechanism with a replaceable soft metal gasket, ensuring reliable performance under extreme pressure, temperature, and vacuum conditions.
These fittings are widely used in semiconductor manufacturing, gas distribution systems, vacuum chambers, analytical instruments, and hydrogen systems where contamination control is critical.
Compared to elastomer sealing systems, metal gasket face seal fittings provide superior cleanliness, lower outgassing, and higher long-term reliability in ultra high purity environments.
