Flange gaskets make these CF flanges self-centering and the standard leak grooves simplify troubleshooting and gasket removal.

OFHC copper gaskets are cleaned, insured to be scratch free, individually sealed, and ready for use. Individual packaging protects flange seal surfaces.

The Viton CF gasket feature a unique notching in the design, allowing less outgassing than most elastomer seals.
