Life Support

Life Support Component Solutions

Hy-Lok USA, Inc. is a critical breathing system fittings supplier, providing life support system components, such as life support needle valves, to the medical, offshore diving, and other critical support system industries.

Our stainless steel fittings are used in pressurized recompression chambers, charging stations, air canisters, breaking air compressors, booster pump assemblies, and analytical instrumentation.

From space applications to firefighting and deep-ocean diving systems, our valves and fittings are tested to the most stringent quality standards, trusted for their reliability in the most critical applications, and designed for use in the harshest environments.

At Hy-Lok, we fully understand the crucial role life support equipment plays in emergency treatments and techniques in various situations where lives are threatened. In situations like cardiac arrest, choking, drowning, accidental injuries, and other emergencies, life support systems can make all the difference.

Flexibility & Design

That is why our products are designed to help healthcare providers, medical professionals, and emergency medical technicians perform lifesaving procedures. In addition to breathing systems, our fittings can be modified for applications such as feeding tubes, mechanical ventilation, dialysis, and even life support systems for human spaceflight.

Life support equipment is typically used in emergency departments, operating rooms, and intensive care units. As technologies improve, however, these systems are increasingly being used outside of hospitals and medical institutions. Home care equipment is another area where Hy-Lok fittings can be modified and utilized.

All valves are 100% factory tested for leaks and we offer custom testing under customer specified environmental conditions. We carry ISO 9001, ASME, PVD, and API quality certifications, and all of our fittings meet API 607/6FA and BS 6755 fire safety standards. In addition, we meet ISO 14001 and OSHAS 18001 standards for safety and environmental protection.
