• Suitable for gas or liquid
• GraFoil™ sealant
• Teflon™ sleeves to protect wires from damage as they exit either end of feedthrough
• 316/316L SST body and 303 SST B cap, different SST grades to minimize potential galling issues

TG assemblies with high-temperature fiberglass-insulated thermocouple wire are specially designed for applications where the sensor wire is exposed to process temperatures reaching up to 1400°F (760°C). This assembly is particularly targeted for use with vacuum and/or inert gas back-filled furnaces with vessel wall temperatures up to 200°F (93.3°C) and pressures not exceeding 300 psi.

The assembly consists of magnesia alumina silicate vitreous fiber braided impregnated thermocouple grade wires on the body side, with stripped bare wires passing through the Conax-manufactured TG Feedthrough. Sleeved insulation material on the wires exiting the cap side may be fiberglass/silicone impregnated or polyolefin.

Gland 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.

Conax Technologies’ HL Feedthrough is designed for sealing protection in a wide variety of hazardous environments.

The HL Feedthrough has been CSA ³ certified in the U.S. and Canada for use in hazardous locations defined by the NEC ² as Class I, Div.1 and 2, Groups B, C, and D; Class II, Div. 1 and 2, Groups E, F, and G; and Class III.

The HL Feedthrough is superior to Chico ⁴ and other similar conduit sealing compound fittings commonly used in hazardous environments.

With a mechanically-sealed Conax HL Gland, you will not have to be concerned about cracks in compound sealants or incorrectly installed compound sealant that allow gases or liquids to leak in the conduit system, migration of explosive gases through stranded conductors due to a pressure differential in the conduit system.

Features:
* CSA ³ certified in the U.S. and Canada
* Pressure rated to 500 PSIg
* Suitable for gas or liquid
* Features Grafoil ¹ sealant
* Sleeves are used to protect wires from damage
* Two body styles – small (1/2″ NPT) and large (3/4″ NPT)
* Body and cap material is 303 SST
* Wire, solid 14, 16 or 18 AWG is supplied either by customer or Conax Technologies
* Minimum 18″ leads on both ends
* Wires can be easily assembled in the field

*Temperature range from -4°F to 130°F (-20°C to + 55°C)

High Density (HD) assemblies consist of a stainless steel tube swaged over 12, 24, 40 or 60 bundled PTFE coated thermocouple grade and/or 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.

HD18 – 0.187″ diameter, 12 conductors
HD25 – 0.250″ diameter, 24 conductors
HD31 – 0.312″ diameter, 40 conductors
HD37 – 0.375″ diameter, 60 conductors

* Sheath Material: 300 Series SST, 4.5″ nominal length
* Temperature Range: -112°F to +250°F (-80°C to +120°C)

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 1/2″ 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.

For other types of high pressure applications such as electrode sealing, please consult the factory.

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

The assembly consists of bonded fiberglass-insulated/silicone 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 1400°F (760°C), see TGM. Sleeved insulation material on the wires exiting the cap side may be fiberglass/silicone 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.
