M1 Octo

The M1 safe second is factory rated for oxygen-enriched mixtures up to 80%. The demand valve body is Zirconium plated brass for fast thermal transfer with a heat sink feature to reduce the possibility of freezing in cold water. The critical metal components of the demand valve are all made of Titanium or 316 Stainless Steel and are completely corrosion proof.
