ATEX / IECEx Approved 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 1.0mm dia., up to 27 x 3.0mm or up to 7 x 6.0mm elements. Please refer to the table for further details of feedthrough capacity and sizes of elements.

There are five body sizes having 1/8”, 1/4”, 1/2”, 3/4” and 1”process connections in either BSPT (conical gas or DIN 2999 ‘R’) and NPT threads.

Spectite® feedthroughs are designed for ease of assembly and installation. Elements can be adjusted, removed and replaced when not under pressure or vacuum conditions.
