We are proud to state that the aerospace industry has been our niche from the start of our organization forty years ago. Helium Leak Testing, Inc. has played a critical contribution for many rocket engines in their development and use. Safety concerns have led to the practice of conducting leak test with helium an inert gas, and try to infer the leak rate of other gases such as hydrogen and oxygen.

All components of the assembled system demand freedom from leakage. Valves, fitting, plumbing, tanks and sensors have all been part of HLT’s testing history.

Space Station Space station seals need to be qualified to eliminate the threat to the crew's safety or to continued operation of the Station and its systems. The utilization of helium leak detectors allows not only the detection of very small leaks but also insures the quality and reliability of the Space Station, reducing the probability of failure. Leak checks also prove that seals and sealing surfaces at joints are defect free and seals are seated correctly.

Satellite thruster control valves and Thruster Nozzles Thrusters are fired to dump the momentum and control positioning. Proper operation of Satellite thruster control valves and leak control is paramount to make the satellite stay in the desired orbit.

Delta rocket fuel filters A major component of aerospace thrusters requires qualification by helium leak testing.

Space simulation chambers Ground support is a necessity for R&D of rocketry vehicles, space stations, and all flight hardware. HLT continually works with corporations to assure high quality simulation equipment.
