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

An almost unlimited selection of either hermetic electrical pin connector types or shielded RF coaxial cables seals are available for either low or high pressures from 1 bar to 1000 bar and low vacuum seals to high vacuums of 10^-8Torr with temperature ranges from cryogenic -200C to 200C, depending upon the design and customer’s actual operating and test requirements.  PAVE hermetic epoxy seals replace hermetic glass to metal connector seals with many more electrical connector design options. In most cases, higher pressures, lower leak rates, and wider temperatures can be accommodated on existing design drawings as well if so needed.

Hermetic connectors include BNC 50 ohm and 75 ohms, SMA both low and high frequency (+2-100 GHz use requires special designs), SHV, SMB, SMC, N, twin axial and more, either dual sided connectors or single-sided styles.  Most connector shields are isolated or floating from the housing or can be ordered grounded. Also, hermetic multi-pin circular connectors and hermetically sealed rectangular combo D-Sub connector designs are also available.

 Virtually any type of coaxial or shielded cable can also be hermetically sealed in most any combination and wire lengths. A wide variety of hermetic feedthrough mounting styles to the bulkhead are available from jam nut o-ring, NPT, piston o-ring, Conflat® flange and more including custom engineered.  There is no detectable leakage of gas or fluids through or around the cables.  We are available to assist with selecting the proper cost-effective hermetic seal design. In a hurry, see our quick ship hermetic seals listing.
