Pressure and Vacuum Sealing Assemblies
Conax Technologies designs and manufactures a complete line of pressure/vacuum mechanical sealing glands and assemblies for wires and probes for virtually every industry. A wide range of catalog standard sealing glands are available from stock, while unlimited custom designs are also available for unique wire or probe sealing applications.

Exclusive "Soft Sealant" Technology
Conax Technologies' exclusive "soft sealant" technology enables easy assembly of the sealing gland by simply inserting the wire or probe and torquing the gland cap. Replaceable sealants permit repeated use of the stainless steel fitting for easy installation and service in the field. Our standard sealant materials include Lava, Teflon®, Neoprene, Viton® and Grafoil® and are designed, depending on gland type, to seal pressures ranging from vacuum up to 10,000 psi/690 bar involving temperatures ranging from -400°F to 3000°F/ -240°C to +1650°C. Other sealant materials are available for custom applications.

Wire and Probe Sealing
In wire sealing, we routinely accommodate in one gland from 1 to 16 conductors ranging from 24 AWG to 3/4"/.03mm diameter to handle a voltage range from the millivolt level up to 8000 volts and currents up to 400 amps. In probe sealing, from 1 to 40 probes, ranging in size from 0.020"/0.5mm to 1.250"/32 mm diameter, are routinely pressure or vacuum sealed in a single unit. Beyond these, we offer custom or special assemblies.

Electrode Gland Teflon (EGT) Glands Electrode sealing glands for gas or non-conductive liquids featuring an electrode encompassed by a continuous Teflon® combined insulator/sealant.
High Density (HD) Mechanically Sealed, Multiple Wire Feedthrough Assembly Continuous wire feedthrough for thermocouples, RTDs and low voltage instrumentation for applications such as sealing of wires exiting glove boxes, pressure vessels, instruments, furnaces, sterilizers and reactors.		Electrode (EG) Glands Electrode sealing glands for gas or non-conductive liquid environments where delivery of high current is required. Applications include electrical feedthroughs for vacuum furnaces, liquid level probes, transformers, reactors, etc.
Transducer (TG) Glands For bare wire sealing against gas or liquids, used for various solid bare wire transducers such as thermocouples, strain gauges, thermistors and resistance element leads. TG-C Wire Seal Termination Assembly This lightweight head provides a convenient and compact method of terminating thermocouple wires and connecting cold end leads. Screw posts, mounted in high purity alumina, securely fasten leadwires in position.		^ Top

Conax Technologies provides four flange styles to accompany its compression seal fittings. All flanges are constructed of 304SST, 316SST or carbon steel. Alternate materials and grades are available – consult with the factory on your requirements
SFA Sanitary Flange Mounts SFA Flange Mounts are designed to mount to Tri-Clover 16 AMP sanitary flanges and equivalent. These mounts provide pressure/vacuum sealing against gases and liquids in pharmaceutical, food and dairy processing.		CF (NW) Vacuum Flange Mounts Designed to mate with Varian Con-Flat®, MDC Del-Seal® or similar vacuum flanges, the Conax Technologies CF Vacuum Flange Mount provides high performance and reliable sealing in all types of vacuum applications.
KF (ISO) Vacuum Flange Mounts KF Vacuum Flange Mounts offer fast assembly and disassembly. They mate to Varian Klamp-Flange®, MDC Kwik-Flange® and similar vacuum flanges. This mounting style is ideal for roughing and high vacuum applications requiring frequent changeover, including sintering furnaces, vacuum furnaces, and semiconductor and powder metal fabrication processes.		ASME/ANSI Flange Mounts Conax Technologies sealing glands can be welded or threaded to ASME B16.5 flanges to create a rugged mounting for environmental sealing and/or securing the position of instrumentation sensor probes. Use of flanges eliminates the need to weld mounting adapters to the pipe or vessel. Common applications include petrochemical processing and distribution, industrial furnaces, bulk cargo carriers, gas sampling coupons and gas storage silos

RTD / Thermocouple Assemblies with Terminal Head and Direct Mount Conax Technologies RTD / Thermocouple assemblies offer a wide variety of terminal head styles to meet application needs. In direct mount models, the sheath is attached to the terminal head using either a W8 fitting or a Conax Technologies manufactured "soft seal" sealing gland. Gland models are provided in different sizes and with various sealant materials to ensure proper function in a wide range of environments. All provided direct mount fittings serve as mounting devices and environmental seals.		RTD / Thermocouple Assemblies with Terminal Heads and Adjustable Mounting Fittings RTD / Thermocouple assemblies can be supplied with a wide variety of terminal head styles to meet application needs. Adjustable mounting fittings using Conax Technologies "soft seal" packing glands allow the immersion depth of the sheath to be easily adjusted in the field and provide pressure or vacuum sealing against gases or liquids. (Glands are shipped untorqued.) Gland models are offered in different sizes and with various sealant materials to ensure proper function in a wide range of environments.
RTD / Thermocouple Assemblies with Terminal Heads and Spring-Loaded Mounting Spring-loaded assemblies are used to maintain positive contact between the sensor tip and the surface to be monitored, typically used with thermowell assemblies. Conax Technologies supplies a number of styles of spring-loaded assemblies to meet application needs. Spring-loaded assemblies can be provided with all terminal heads. In addition, the T11SL model provides a spring-loaded assembly built into the T11 aluminum terminal head.

Our high temperature thermocouples are specifically designed for durability and reliability in high temperature applications to 4200°F (2315°C). Such applications involve oxidizing, reducing, inert gas or contamination atmospheres that challenge the life of the thermocouple. Tungsten-Coated Molybdenum for Graphite-Lined Furnaces At temperatures above 2012° F (1100° C), graphite dust from graphite liners/shields or heating elements can attack and carburize molybdenum sheaths. This causes the sheath to crystallize and become porous, losing its protective properties. The thermal elements in turn crystallize and open. Coating the heat-affected length of the molybdenum sheath with a thick layer of tungsten reduces this carburization action and extends probe life. The tungsten coating also provides increased abrasion resistance.

Thermowells are pressure-tight receptacles that extend the life of a temperature in environments where the sensor is not chemically compatible with the process media or the sensor does not have the mechanical strength to withstand the process flow or pressure. Thermowells also facilitate removing, changing, checking or replacing sensors without draining the process system. The use of standardized thermowells throughout a plant permits easy relocation of sensors.

High Performance Applications: Conax Technologies Con–O–Clad® is manufactured using high performance/exotic alloys for critical applications where performance under extreme temperatures or severe environmental conditions is required.
