Ultra-Thin, Ultra-Hard, Surface Enhancement Applied On International Space Station's Quick Disconnect Couplings Eliminates Wear, Leaks, and Contamination

In the harsh vacuum and low temperatures of outer space, the valves on quick disconnect couplings (QDCs) on the International Space Station (ISS) must operate with total reliability. Even UPS or FEDEX haven¹t found a way to make an overnight delivery of a replacement part to outer space. That's why the QDCs must be extraordinarily smooth, hard, and durable to alleviate the possibility of damage to the sealing surface during transportation or simply when opening or closing valves at temperatures as low as -160°F (-107°C).
