Description
Kaxite's OFHC copper gaskets for CF flanges are precision-engineered sealing components designed for ultra‑high vacuum (UHV) and high‑purity applications. As a leading CF Flange Gaskets Supplier in China, we manufacture oxygen‑free high‑conductivity copper gaskets that deliver exceptional leak‑tight seals between ConFlat flanges. Our copper gaskets for vacuum applications are crafted from premium OFHC copper, offering superior cleanliness, excellent formability, a wide temperature range from cryogenic to elevated temperatures, and extremely low outgassing rates – making them the ideal choice for semiconductor manufacturing, research laboratories, and industrial vacuum systems. Available in standard CF sizes from CF16 to CF250, with full customization options for non‑standard dimensions, Kaxite ensures consistent quality, fast delivery, and ISO 9001 certified reliability for all your vacuum sealing requirements.
To make a leak tight UHV seal between two conflat flanges, a gasket is required. OFHC (oxygen free high conductivity) copper is normally used as this sealing material as it is very clean, can easily be formed to shape, has a wide temperature range, and has a low outgassing rate.
