What tubing is used for medical gas service?

The use of degreased and dehydrated tubing marked for oxygen service is critical in medical gas systems due to safety and health standards. Oxygen is highly reactive and can support combustion; thus, any tubing used must be free from contaminants such as oils or greases that could potentially ignite. The marking for oxygen service ensures that the tubing has been specially treated and tested to meet the stringent requirements necessary for safely handling medical gases like oxygen.

In contrast, PVC tubing is not designed for high-pressure medical gas systems and could compromise the integrity of the system. Stainless steel tubing is often used in various applications, including some medical gas systems, but while it is resistant to corrosion and contamination, it typically isn't specifically marked for oxygen service as required here. Polyethylene tubing, on the other hand, isn't suitable for high-pressure medical gas applications due to its susceptibility to leaks and lack of the necessary certifications for direct contact with medical gases.

Therefore, the choice of degreased and dehydrated tubing marked for oxygen service is essential in ensuring reliability and safety in the delivery of medical gases.
