High-Pressure, High-Temperature Harsh Environment Connectors
Resolving Gas, Moisture and Particle Ingress
Problems in Geophysical Applications with
High-Temperature Glass Hermetic Connectors
I
nterconnection devices permanently sealed by glass fusion are ideally suited to prevent
the transmission of air, moisture, and other gases into electronic equipment used in
downhole and other well completion applications. Hermeticity is expressed as the rate
of leakage volume of helium per second in time, and glass-to-metal seal technology
achieves highest possible hermeticity ratings (up to 1x10-10 CC He/Sec.) High temperature
vitreous glass is used to provide a robust hermetic seal between metal conductors
(contacts) and metal connector shells. Glenair is the recognized worldwide leader in the
design and manufacture of high-reliability glass hermetic connectors, and can integrate
the technology into virtually any connector package or series.
Advantages of glass-to-metal sealed hermetic
connectors compared to potted plastics or
elastomers in hostile environments
Enhanced reliability
Superior pressure resistance to 32,000+ PSI
Higher resistance to extreme operating temperatures
to 260°+ C
Superior mechanical strength
No material breakdown or aging over time
Improving Durability and
Total Cost of Ownership for Oil Patch
Connectors and Cables
D
esigned for use in geophysical and other hostile marine and oilpatch applications, Glenair’s Series 22 Geo-Marine® connectors,
cables and bulkhead feed-thrus offer high-density insert arrangements
and advanced environmental sealing. Specialized corrosion-resistant
materials increase system integrity and lower system cost. Standard
mated stainless steel plugs and receptacles deliver a hydrostatic
pressure sealing capability of up to 5000 psi (345 bar) and are available
in either glass-sealed hermetic or with rigid dielectric environmental
insulators. Customized HTHP Connectors can be engineered with
Inconel® body/pin materials or other exotics. Other features
include single-start, stub-Acme threads for quick
coupling and superior resistance to thread
fouling and binding due to dirt and other
foreign matter; a castellated and knurled
plug coupling ring which provides easy
mating and unmating, even with arctic
gloves; and plug shell leading edge
configuration which assures
key-keyway alignment and
engagement prior to mating
of the plug coupling
ring threads.

High Temp Micro-D
Glenair Well-Master™ 260—The Micro-D
Connector for Serious, High-Temperature
Applications
260° continuous operating temperature
Angled mounting ears for easy fit in cylindrical equipment housings
High-reliability TwistPin contact system utilizing special hightemperature alloys on .050” pitch contact spacing

tandard Micro-D connectors are rated for +125°C. Glenair’s MWDM Micro-D can withstand +150°C continuous
operating temperature and can be upgraded to +200°C if assembled with special high temperature epoxies.
(Glenair, by the way, is the world’s largest manufacturer and supplier of these standard-duty Micro-D connectors).
But oil, gas and geothermal wells can subject electronic instruments utilizing these miniature connectors to
temperatures as high as +260°C or more. The GHTM (Well-Master) Series Micro-D meets this need for a high density,
high performance connector capable of handling extreme temperatures. Well-Master contacts are made from a
special alloy that resists softening when exposed to high temperatures. Rugged passivated stainless steel shells and
hardware, high temperature liquid crystal polymer (LCP) insulators and special epoxies allow these connectors to
survive the most demanding high-temperature environments. Consult factory for high-temp versions up to 300°C.
