Oxygen Environments in Medical Applications

Medical grade lubricants are crucial parts of the healthcare industry. They are especially useful in applications involving oxygen, which are prone to fires when incompatible technologies are used. Oxygen-rich environments are present in many medical applications, including:

  • Oxygen ventilators – used for the treatment of respiratory conditions such as COVID-19
  • Nitrous-oxide sources, which thermally decompose to oxygen
  • Oxygen & gas cylinders

Such applications require extra care when maintaining. Most conventional lubricants and greases have a tendency to self-ignite when coming into contact with oxygen-rich environments. This leads to extremely dangerous situations which can be avoided if the lubricants used are non-reactive; leading to strict regulations when it comes to which lubricants you can use.

Krytox Lubricants for Oxygen Environments

Krytox lubricants are particularly well-suited to oxygen-rich environments by being:

  • Non-flammable – eliminating requirement for fire-prevention systems
  • Thermally stable – providing excellent lubricity at extreme temperatures
  • Chemically inert – safe when used with other oxidising agents such as fluorine, bromine and chlorine
  • Safe for use in all areas of oxygen service – 100% compatibility

Additionally, Krytox performance lubricants have been approved by the West German Federal Institute for Materials Testing (BAM) for use in cryogenic pumps, oxygen equipment ranging from scuba diving kits to NASA equipment, vacuum pump fluids, and cryogenic blowers, bearings, O-rings, compressors and fittings. 

Medical Grade Lubricants

Krytox offers different ranges of lubricants and greases which can be adapted to medical systems. These lubricants meet the strict standards listed above and allow medical equipment manufacturers to efficiently and effectively manufacturer safe and reliable performance over the long-run.

Krytox XHT Lubricants

Krytox XHT-BDX Grease is an extreme temperature grease which provides excellent lubricity in a large range of applications. It has little or no risk when used with metals and can easily be used on metallic surfaces; making it a versatile lubricant that can be utilised in varying medical device applications.

Krytox XHT-BDZ Grease is another extreme high-temperature grease designed for use in applications surpassing 288 °C, where standard PTFE thickeners are in danger of melting. It is commonly used in low-speed bearings and pillow housings.

Krytox NRT (non-reactive) Greases

Krytox NRT 8904 is a non-reactive, long-lasting grease designed for use with reactive gases such as oxygen, which makes it a valid option for manufacturers who are looking to boost product performance whilst still meeting strict industry regulations. As well as it’s oxygen compatibility, it is also suitable for use in demanding temperatures and pressures. It is commonly used in regulators, pumps, valves and compressors.
