[Breech Coupling, MIL-C-38999
Series IV Type]
Class-S Space-Rated
Connectors
NASA Threaded Coupling (NATC)
SG3 Series
The G&H Technology SG3
Series of NATC connectors meets all of the physical and electrical requirements
of NASA Specification SSQ 21635, using space-rated materials acceptable
for manned spaceflight environments. They are scheduled to be used extensively
throughout the International Space Station
These rugged high-reliability
products are suitable for a wide variety of space applications. The
coupling nut anti-rotation system prevents loosening without the use
of lockwires.
The connectors feature complete
environmental sealing. All elastomeric materials are space compatible
and outgassing is minimized.
Qualification Status:
Approved for manned space
flight by NASA Johnson Space Center, International Space Station Program.
Full compliant with NASA Specification SSQ 21635
