Compression Seal Fittings

Very High Density Feedthrough

Large Scale Field Rebuildable

Customer Requirement:
A pump assembly facility needed a compression seal fitting capable of sealing 80 Tefloninsulated, 24 AWG, Type J thermocouple wires (40 pairs) in nitrogen gas at 3750 psi and
205°C. The customer required the performance of hydrostatic pressure test at 3750 psi
and 21°C for 10 minutes with no visible leakage or wire movement permitted. A certificate
of conformance was also required.

Customer Requirement:
An aerospace composite parts manufacturer, wanted to replace their heater power feedthrough
in an aerospace parts autoclave that incorporated a design to allow a field rebuild.

Conax Design Solution:
Conax used its new MHM6 sealing gland with a Grafoil® sealant. The assembly contained
120" leads on the body side. The Conax description is MHM6-24T(J)-A80-G, 120"/24".
The customer said that Conax was the only vendor capable of sealing 80 wires for this
high pressure application.

Conax Design Solution:
This product is a customdesigned large-scale
hybrid of our Electrode
Gland (EG) series and our
Electrode Gland Teflon
(EGT) series designs.
We combined positive
features of each fitting
to benefit the customer
in this application. The EG
offers high temperature resistance required closer to the heaters.
The EGT offers more robust, less costly components for the balance
of the assembly located where lower temperatures prevail.

Very High Pressure Feedthrough

Durability in a Corrosive Environment

Customer Requirement:
A manufacturer of fluid ends (pump suction and discharge components) for high-pressure oil
field pump service applications required a compression seal fitting that could seal the strain
gauge leads exiting the fluid ends and hold up under pressures in the 30,000 psi range.

The Complete Guide to Vacuum and Pressure Seal Assemblies

Customer Requirement:
A semiconductor customer required high quality wire sealing in a demanding highly
accelerated stress testing (HAST) application that included corrosive materials attacking
the seal, insulation and wires.

Conax Design Solution:
Our Conax Oil & Gas team accelerated an engineering program to develop a new high
pressure gland (HPPL). The HPPL gland incorporates a body manufactured from high
strength stainless steel, a high pressure mounting thread and our soft sealant technology
to seal up to 10 Kapton® - insulated 26 AWG solid copper conductors. Conax is one of the
few companies with the capability to seal wires at ultra-high pressure and provide a gland
that can be rebuilt with new wires.

See page 75
Conax Design Solution:
Our Conax Semiconductor team developed this high density (HD) style feedthrough
featuring 24AWG, Teflon insulated wires – and may come in copper, or as J, T, K or E
thermocouple calibrations – mixed or matched. Multiple high density tubes in 12, 24, 40
and 60 wire densities may be grouped together in a common sealing gland to minimize
penetrations. Other design options are available for feedthroughs and connections.
