Pressure and Vacuum Feedthroughs

Series MF - Feedthroughs for multiple elements

A single access port into an enclosure or process vessel is all that is needed to allow multiple probes, sensors, etc., to pass through an environmental or pressure boundary using a single feedthrough assembly.

Series MF feedthroughs can seal multiple elements within a single assembly including typically up to 40 x 0.040” dia., up to 12 x 0.125” or up to 4 x 0.250”. Please refer to the table for further details of feedthrough capacity and sizes of elements.
