High Density (HD) assemblies consist of a stainless steel tube swaged over 12, 24, 40 or 60 bundled PTFE coated thermocouple grade andor copper wires, providing a continuous wire feedthrough for thermocouples, RTDs or low voltage instrumentation. No epoxy or potting is used in the construction. The assembly can be furnished with or without junctions and comes standard with 24 inches of leadwire on each end. Longer wire lengths can be supplied as required. A single high density feedthrough can pass through a Conax PG Fitting for environmental sealing. Greater density through a single port can be achieved by using a Conax MHM Fitting that accommodates multiple HD assemblies.

Conax Technologies designs a PG9 compression seal fitting to seal on an analyzer probe of various thicknesses. One application example called for a specialized Conax PG9 Fitting with a steam jacket to seal a 1.25 pipe (1.66 OD) to hot-tap a sulfur analyzer probe into a sulfur recovery unit (SRU) tailgate process. The steam jacket around the fitting maintains the temperature at 300F (149C) in order to prevent the sulfur from hardening and cementing the probe in place. Utilizing similar engineering capabilities, Conax can also design a water cooled compression seal fitting for high power electrical feedthroughs.

Conax Technologies Model PG Packing fittings provide pressurevacuum sealing for tubes, process pipes, cable 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.

TG assemblies with fiberglass-insulated thermocouple wire are specially designed for applications where the sensor wire is exposed to process temperatures reaching up to 900F (482C). This assembly is particularly targeted for use with vacuum andor inert gas back-filled furnaces with vessel wall temperatures up to 200F (93.3C) and pressures not exceeding 300 psi.

The assembly consists of bonded fiberglass-insulatedsilicone impregnated thermocouple grade wires on the body side, with stripped bare wires passing through the Conax-manufactured transducer gland. An alternative high-temperature fiberglass for Type K wire is also available with temperature capabilities up to 1400F (760C), see TGM. Sleeved insulation material on the wires exiting the cap side may be fiberglasssilicone impregnated or polyolefin.

Feedthrough bodies, caps and followers are constructed from 303SST. Cap Style A offers a mounting thread only. Cap Style B provides threading on both ends for attachment to conduit or terminal heads. These assemblies are offered with Viton sealants. Alternative sealants are available. Please consult a Conax Technologies sales engineer for custom needs.

Continuous Wire Feedthrough for Embedded Bearing Temperature Sensors while sealing securely to prevent oil wicking along the leads.

Conax Technologies BEARING SENSOR WIRE SEAL efficiently seals directly on the individual insulated leads of an embedded bearing temperature sensor exiting an oil-filled bearing housing.

Typical applications include the sealing of these leads on large motors, generators, turbines, pumps, compressors and journal bearing pedestals.

* For Bearing Oil Sealing
* Easy Installation No Potting
* Seals 2 to 14 Wires
* Pressure: to 50 PSI (3.4 bar)
* Temperature Range: Ambient to 100F (37.8C)
* Field Adjustable
* Reusable Fitting

At the opposite end of the product spectrum, Conax Technologies also produces affordable, high integrity sealing solutions where high pressure, temperature or vacuum is not required. A good example of this type of solution is the brass feedthrough that was developed for the automotive industry. This feedthrough was designed for use as a wire seal on aftermarket air suspension products for performance automotive use. The unit normally operates at 40 to 60 PSI to a maximum pressure of 100 PSI but is also capable of accepting transient spikes to a maximum of 150PSI. Ambient temperature operating parameters are from -20C to 80C. The unit will accept up to four 18 AWG wires and has a .25NPT male process connection. In addition to the automotive industry, other industries such as aerospace, transportation and industrial machinery will find these types of sealing solutions very useful.

Conax Technologies manufactures high pressure seals up to 30, 000 psig at 68 F (20 C) for instrument signal wires. High pressure seals are designed for installation onto the pressure vessel wall using threaded mounting configurations only. High pressure assemblies are factory torqued, so disassembly and reassembly in the field is not recommended.

These assemblies feature body and caps constructed from high strength 316SST and a proprietary sealant. HPPL assemblies are provided with Kapton-insulated 26 gauge solid copper wire. Standard assemblies include 24 of wire on each side. To order other wire lengths, indicate the desired lengths after the catalog number.
A 12 NPT thread can be added to the assembly cap to allow mounting a terminal box or other type of enclosure. Consult factory for ordering details.

When your requirement calls for sealing on jacketed cables, Conax Technologies PG Double Sealant Fitting is the ideal solution. Our PG fitting is modified to accept standard PG sealants inserted into the fitting back-to-back and compressed with a shortened. Pictured is an actual test fixture. Note the reduced compression on the semi-rigid cable using the double sealant design. The design advantage of this gland is that there is an equal seal capability on an extended length of the cable so that each seal requires less compression while offering equal or greater pressure retaining capabilities. Send us a length of your cable. Conax has the in-house pressure testing capabilities to validate an engineered solution. The model number example with two viton sealants is PG5-625-A-VV.
