Series PSF and MSF- Split Feedthroughs for single and multiple elements
Pressure and Vacuum Feedthroughs
Series PSF (single element) and MSF (multiple elements) feedthroughs are similar to series MF feedthroughs, but have split internal components.
This permits elements, that have a larger diameter section other than at the sealing point and can pass through the feedthrough body but not through the internal components, to be installed easily. Examples are probes with fitted connectors and sensors with pot seals or bulbs.
There are three body sizes having 1/4”, 1/2” and 3/4” 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.

- The guide pressures shown for each type of sealant are at 20°C. Spectite® feedthroughs from TC Ltd. have been designed to provide an efficient seal on the elements and restrain them from moving under pressure and vacuum. It is good installation practice to provide additional, mechanical restraint to the elements when differential pressure exceeds 50% of the feedthrough guide pressure value at 20°C. With an increase in temperature, a reduction in the maximum guide pressure value can be expected. These ratings are a guide and the suitability of any of the products described herein for a particular application is entirely at the discretion of the purchaser as being the best judge for that particular application.
- Other types of process connection are available, see Feedthrough Sizes.
- The element diameters shown are the common sizes routinely demanded for general industrial applications. Other sizes can be supplied between the minimum and maximum diameters shown.
