What type of lubricants are generally recommended for use with enriched air?

The use of oxygen compatible lubricants is crucial when working with enriched air (oxygen-enriched mixtures), primarily because these lubricants are specifically formulated to be safe in high-oxygen environments. Oxygen can react with certain organic materials, potentially leading to combustion or degradation of the lubricant, which can pose significant hazards during diving operations.

Oxygen compatible lubricants are free from substances that could ignite or break down under oxygen-rich conditions, ensuring that equipment remains functional and safe under the pressures and conditions found while diving with enriched air. They maintain their integrity and effectiveness, protecting O-rings and other seals, while preventing potential reactions that could occur with other types of lubricants.

Using non-oxygen compatible lubricants, such as heavy-duty lubricants or standard grease, could increase the risk of fire or equipment failure. Similarly, water-soluble products are not suitable because they can wash away, leading to inadequate lubrication when sealing important components. Therefore, prioritizing oxygen compatible lubricants is essential for the safety and reliability of diving gear when using enriched air.
