PAVE hermetic seals and bi-directional and will seal both pressure and vacuum in either or both directions. For pressures above 300 psi (20 bar), please check with the sales engineer if changing the pressure direction shown on the drawing.

Thermocouple feedthrough hermetic seals are for low or high vacuum and pressures of any type of solid conductor Teflon® or glass braid insulated thermocouple wire pairs with hermetic seal temperature ranges between -200C to 200C depending on the design or customer requirements. All types of thermocouple cable are available hermetically sealed including K, T, J, E, N, RxSx and to any combination or cable lengths as well as shielded cables. The thermocouple cable conductor remains continuous through the hermetic seal that allows for the highest temperature accuracy. Welded wire junctions can also be ordered. Multi-pin hermetic connector versions are also available. Both standard and custom design hermetic seal designs are available for both small and large quantities with a variety of mounting styles and cost-efficient designs, O-ring face or piston seals, NPT seals,

Both standard and custom design hermetic seal designs are available for both small and large quantities with a variety of mounting styles and cost-efficient designs, O-ring face or piston seals, NPT seals, Conflat ®, ISO and custom flanges including electron beam or laser weld. Our hermetic epoxy cable seals are highly resistant to solvents, fuels, fluids, and gasses.

Also, our epoxy hermetic seal is NASA approved for low outgassing in high vacuums up to 10^-8 Torr. See our Quick Ship Feedthru List. Please contact us for assistance or new designs.
