Seals for high pressure applications

Conax Technologies manufactures high pressure seals for electrodes, instrument signal wires and temperature sensor leads. High pressure seals are designed for installation onto the pressure vessel wall using threaded mounting configurations. A 1/2” NPT thread or ‘B Cap’ can be added to the HEGPK and HPPL assemblies to allow for mounting to a terminal box or other type of enclosure. These assemblies feature body and caps constructed from high strength 316SST.

These products are for high pressure applications; please contact Conax directly if you need to seal on other elements within different environments. The following are examples of typical fittings or feedthroughs we offer for high pressure applications.
