High-Pressure Assemblies for Pure Gas Pneumatic/Cryogenic Applications
Series 831 GT assemblies provide passage of nitrogen and other pure, pressurized gases
through standard MIL-DTL-38999 Series I, III and IV connectors. These snap-in, rear-release
assemblies feature precision stainless steel gas contacts brazed to semi-rigid stainless steel
tubing. The assemblies are fabricated using a flux-free brazing process and are ultrasonically
cleaned and packaged in a sealed, dust-free environment. Available in #12 AWG gas contacts,
these assemblies are supplied with two different tubing sizes, and may be ordered in single
ended or pin-to-pin, pin-to-socket and socket-to-socket configurations. Consult factory for
available off-the-shelf lengths or use the part number to specify a made-to-order length.
#12 assembly for MIL-DTL-38999 Series I, Series III and Series IV environmental connectors. Use part number

Flow Rate
Typical Flow Rate is 5 liters per minute
(lpm) @ 150 PSI.
After cycling the connector between
-65°C +175°C, gas contacts will meet all
applicable mechanical requirements.
No mechanical defects after 500 cycles of
engagement and disengagement.
No loosening of parts, cracking or other
deleterious results hindering further
part operation after 300 G's in each of 3
mutually perpendicular planes.
Mated connectors will withstand high
impact shock per MIL-S-901.
No disengagement of mated contacts,
backing off of the coupling mechanism,
evidence of cracking, breaking or
loosening of parts.
