Hybrid Adapters – Vacuum Flange & Fitting Transition Solutions

MDC's Hybrid Adapters are precision-engineered components designed to connect vacuum systems with dissimilar sealing geometries. Each adapter includes two different interfaces—such as a metal-seal flange and an elastomer-seal fitting—allowing flexible system integration. These components are ideal for applications requiring transitions between Conflat®, ISO, ASA, VCR®, or Swagelok® connections.

There are two main categories:

Flange-to-Flange Adapters, which bridge two standard vacuum flanges (e.g., ISO to CF)
Fitting-to-Flange Adapters, which join standard vacuum fittings to flanged applications

Adapters with O-ring seals are high vacuum rated to 1x10⁻⁸ Torr (1.33x10⁻⁶ Pa) and withstand bakeout temperatures up to 200°C. MDC’s Del-Seal™ CF to VCR® or Swagelok® designs are UHV-compatible, supporting pressures to 1x10⁻¹⁰ Torr (1.33x10⁻⁸ Pa) and temperatures up to 450°C. Custom hybrid solutions are also available upon request.

Industry Applications

MDC Hybrid Adapters are used across semiconductor processing, vacuum metallurgy, accelerator labs, and space simulation systems. These components allow researchers and engineers to connect legacy equipment with modern vacuum interfaces or accommodate specialty ports and instrumentation without system redesign. They are essential in high or ultra-high vacuum environments requiring flexible geometry adaptation.
