MDC Europe hybrid adaptors provide a transition from one method of sealing to another. The hybrid feature of these adaptors is that the geometries at each end of any component are different. This is more than a change in size within a particular sealing method. They are available in most of the common interface transition pairs.
There are two major categories of adaptors: one combines pairs of standard vacuum flanges and the other combines standard fittings with flanges.
A frequent transition is from a metal seal flange to an 0-ring sealed flange or fitting. Specifications are generally limited by the introduction of an 0-ring seal. All hybrid adaptors, except the CF to Swagelok® or VCR® adaptors, include at least one non-metal seal and are therefore limited to high vacuum applications. Refer to individual component sections for specifications.

Reducers are a change in size within a particular flange sealing method, such as metal-seal to metal-seal. Reducers within a specific sealing method can be found in the fittings portion of each flange section.
