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.

Individual elements can be replaced without complete disassembly

Internal components – follower, sealant and seat are split to allow easy installation of elements with fitted connectors or large diameter sections.

Designed to carry single elements 1.0mm to 12.7mm dia., and multiple elements 1.0mm to 6.35mm dia.
