How should I inspect and lubricate O-rings on a CCR?
O-rings provide critical seals in a CCR and must be correctly selected, inspected and lubricated with oxygen-compatible products where required.
O-rings are an industry standard for sealing tools in the SCUBA diving world. The efficiency lies in the elastic and water-resistant material. Since rebreathers use Oxygen it is crucial to always use Oxygen compatible lubricants and O-rings for any use with rebreathers in order to prevent Oxygen fires. This critical component will be covered in your introductory rebreather course and in your advance Nitrox class.
