High Temperature Series Five connectors are the ideal solution for interconnect and electrical wire assemblies near engines, firewalls, and other high-heat sources. Built for applications with higher temperatures such as hypersonic weapon systems, small module nuclear reactors, space launch vehicles, and other advanced aircraft, these high-heat connectors are built to operate under temperatures up to 572 °F (300 °C) for longer durations, with continuous duty at 500 °F (260 °C) assured. Using proven high-heat materials such as alumina ceramic inserts, high-temperature elastomeric seals, and much more, High Temperature Series Five connectors can beat the heat. 

The heat-resistant High Temperature Series Five outperforms standard mil-spec D38999 connectors under similar high-heat circumstances. Temper-Grip socket contacts come standard to ensure a ruggedized connection even during firewall testing of more than 2,000 °F (1,093 °C). 

This high-temperature technology is available for other connector series too, such as MIL-DTL-38999 Series III.

As today's advanced propulsion systems achieve higher-and-higher speeds, the demand for connectors that can sustain high-heat environments has never been greater. High Temperature Series Five is the ultimate solution for high-heat applications that demand durability, reliability, and resistance to extreme heat.
