How often should oxygen regulators be oiled?

Oxygen regulators should never be oiled because introducing oil to oxygen systems presents a significant safety hazard. Oxygen is a highly reactive gas, and when it comes into contact with oil or grease, it can ignite spontaneously or contribute to rapid combustion. This can lead to dangerous explosions, particularly when high pressures are involved in oxygen systems.

For this reason, it is essential to keep oxygen regulators and other oxygen equipment free from any contaminants, including oil. Regular maintenance may involve visual inspections and ensuring that the equipment is functioning properly, but applying oil is strictly prohibited. Thus, understanding that oil should never be used helps ensure safe practices when working with oxygen equipment.
