Description
Kaxite's OFHC copper gaskets are precision‑engineered sealing components manufactured from oxygen‑free high‑conductivity copper, delivering exceptional leak‑tight performance in ultra‑high vacuum (UHV) and high‑purity applications. As a leading OFHC Copper Gaskets Supplier in China, we produce high‑quality copper seals that meet the most demanding requirements of semiconductor manufacturing, research laboratories, and industrial vacuum systems. Our custom copper gaskets are available in a comprehensive range of materials including OFHC copper, silver‑plated copper, gold‑plated copper, aluminum, fluorocarbon, and nickel – each selected for specific application needs. With outstanding cleanliness, excellent formability, wide temperature range from cryogenic to bake‑out conditions, and extremely low outgassing rates, Kaxite's OFHC copper gaskets are the preferred choice for critical sealing applications where reliability and purity are paramount. Available in standard CF sizes from CF16 to CF250, with full customization for non‑standard dimensions, we ensure consistent quality, fast delivery, and ISO 9001 certified reliability.
OFHC Copper Gaskets for CF Flanges
We manufacture a full range of OFHC Copper, annealed copper, aluminum and gold and silver plated, and elastomeric fluorocarbon gaskets for CF flanges. Metal gaskets are impermeable to gases and withstand moderately high temperatures indefinitely. The CF flange is the most widely used for high vacuum and UHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.
