Can I use a Cyklon, Jetstream or Xstream Deep regulator with nitrox?
The Cyklon, jetstream and Xstream Deep are certified and approved with gas mixes that contains a maximum of 21% oxygen. The mentioned regulator models have Nitril o-rings and a silicon based lubricant is used. So it’s not suitable for gas mixes that has higher levels of oxygen. If you intend to dive Nitrox, you should use the Xstream Duration, that is approved for gas mixes with a maximum of 99,95% oxygen.
