Single element compression seal fittings

Conax Technologies’ single element fittings are used for sealing on a single element, such as a temperature probe, wire, electrode, tubewell, pipe, etc. These fittings are capable of sealing on items made of metal, glass, ceramic or plastic. Visit our website to learn about all of our standard and customized fittings and feedthroughs.

PG series seal fittings

PG series provide pressure/vacuum sealing for tubes, probes, pipes, cables or any single element assembly (not electrically isolating), including thermocouples, RTDs, thermometers, thermistor probes, capillary tubes, tubewells, multi-pair cables, and analyzer sample tubes. PG fittings seal against gases and liquids and resist element movement under pressure. Element diameters range from 0.040" (1.0 mm) to 1.50" (47.5 mm) pipe.

HPG high-performance seal fittings

High-performance HPG series fittings are especially well suited to the unique conditions found in furnaces, autoclaves, environmental chambers, oil and gas applications, and chemical and biochemical reactors where process temperatures and pressures combine to create challenging environments. Employing PEEK® as a sealant material, the HPG fitting offers unique properties, such as chemical resistance rivaling PTFE, higher operating temperatures, a lower expansion rate, and little to no cold flow. Element diameters range from 0.040" (1.0 mm) to 1.50" (47.5 mm) pipe.

Midlock series fittings

Conax Model MK midlock fittings seal a single tube or probe. Featuring a metal-to-metal seal rather than our standard soft sealant technology, MK fittings are used where a joint must be opened and resealed in the same setting. Their unique design forms the seal well within the body housing to provide superior performance in high vibration applications. The single ferrule is self-aligning to eliminate the risk of lost pieces.

Electrode series fittings

Model EG series single electrode compression seal feedthroughs are designed to conduct rated amperage through vessel walls for applications such as vacuum furnaces, autoclaves, transformers, power supplies and other vessels requiring a sealed environment. EG feedthroughs electrically and/or thermally isolate single electrodes, tubes, temperature sensors and liquid level probes in pressure/vacuum applications. These bare electrical feedthroughs seal against gases and liquids and resist element movement under pressure.

Electrode PTFE series feedthroughs

Conax EGT series and HEGPK series feedthroughs electrically and/or thermally isolate single electrodes, tubes or temperature sensors for use in vacuum furnaces, liquid level probes, transformers, environmental chambers, power leads and more. These bare electrical feedthroughs also seal against gases and liquids and resist electrode/conductor movement under pressure. The HEGPK Feedthrough differs from the EGT feedthrough in that the single piece insulator/sealant is manufactured from PEEK™.

Split compression seal fittings

Split (PGS series) fittings seal cables and leads when larger probes or connectors are attached. Split fittings provide split sealants, followers and seats to facilitate easy sealant change without removing the element(s) from the system. Possible applications include sealing analyzer sampling probes with blow-out collars, gas-filled capillary bulb temperature sensors, and cable assemblies with factory-installed connectors, or to facilitate assembly and disassembly of long cable/sheath lengths.

Soft sealant technology, pioneered by Conax

Thanks to our soft sealant technology, Conax fittings maintain constant compression around wires, probes, and electrodes throughout the life of the seal to minimize risk of gas or liquid leaks. Soft sealant technology also makes installation, replacement and adjustment of wires, probes, and electrodes possible.
