Pressure and Vacuum Feedthroughs

Series WF - Feedthroughs for multiple wires and probes

When multiple wires must pass through a pressure boundary, series WF feedthroughs can provide an efficient seal without recourse to epoxies or other non-adjustable fixture methods.

Assemblies may be specified according to the type of element required to pass through the feedthrough and are suitable for up to 12 bare or insulated wires - sizes from 24 to 8 AWG..

Insulators within WF feedthrough assemblies protect bare wires and provide additional isolation for Kapton® insulated power wires. These are rated max. 55A @ 600Vdc/850Vac max. Feedthroughs with power wires can be supplied as complete assemblies, ready for installation, with wires cut to specified lengths.

WF feedthroughs can also accommodate up to 12, small diameter sensor elements that must be electrically isolated from each other.
  • Seal on Kapton® insulated copper or thermocouple wires – type WFS
  • Seal on bare wires carrying instrumentation voltages – type WFR
  • Seal on small sheathed sensors, max. 0.125” dia. – type WFP
  • Pressure range: Vacuum to 10,000psi *
