MDC’s Conflat® to Kwik-Flange™ KF Hybrid Adapters enable seamless transitions between metal-seal and elastomer-seal vacuum interfaces, accommodating diverse system requirements. These high vacuum-rated components connect Conflat® flanges (CF) to ISO KF (Kwik-Flange™) ports, facilitating compatibility between legacy UHV equipment and quick-connect systems.

Each hybrid adapter features a symmetric, nonrotatable geometry and is constructed from 304 stainless steel. The KF side incorporates an FKM elastomer O-ring seal, making it ideal for high vacuum use up to 1x10⁻⁸ Torr (1.33x10⁻⁶ Pa). Adapters are bakeable to 200°C, supporting demanding lab and industrial vacuum environments.

For unique connection needs not addressed by standard offerings, custom hybrid adapters are available upon request through MDC’s technical sales team.

Industry Applications

MDC CF to KF hybrid adapters are widely used in vacuum research labs, OEM manufacturing, semiconductor tools, and vacuum instrumentation setups requiring flexible interface compatibility. Their ability to bridge UHV-grade metal seals with quick-connect elastomer seals makes them essential for retrofitting equipment, connecting gauges or sensors, and enabling modular system design.
