Memorable Moments:

  • In the 1990s we patented and licensed a "Minimum-Dead-Volume Fitting" design, which was the basis for the world-wide "W-Seal" industry as it is know in semiconductor circles today;
  • Our "Anti-Torque-Rings" were used by the Jet Propulsion Lab on the MSL Mars Rover, "Curiosity", which landed on Mars in 2012;
  • A gas control panel using our Circle Seal Valves was seen on Ted Kopple's: "Nightline" Program;
  • Hy-Tech's "Mini-Weld-Fittings" were used by NASA on Astronaut Propulsion Packs;
  • We were the first to introduce electropolished,stainless steel, Grooved Gaskets to the semiconductor industry;
  • Hy-Tech developed low- cost "Shipping Caps and Plugs", which were approved by Applied Materials, saving them millions of dollars;
  • We developed a novel "Recycling Program" for the shipping caps and plugs which was praised in Applied Materials newsletter.
