These feedthroughs are designed for sealing single elements, usually sensors, probes or tubes, where they penetrate a pressure or environmental boundary.

Common applications include sealing sheathed thermocouples and resistance thermometers, small-bore tubes and other types of sensor where they enter a process enclosure.

Series PF feedthroughs seal elements from 0.5mm dia. to 19.05mm (3/4”). There are four body sizes having 1/8”, 1/4”, 1/2” and 3/4” process connections with 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.
