Description

In a compartmentalised case, the OMS Divers’ O-Ring Kit contains 16 of the most common O-rings (over 200 O-rings), from HP swivel to tank neck O-rings.

The O-Ring Kit comes with two o-ring picks and an o-ring size key.

• NBR (Nitrile): Standard for most scuba applications.

• Viton (FKM): Highly resistant to chemicals and heat; better for high-percentage Nitrox or Oxygen-serviced systems. Less degradation than standard Nitrile.

• 70 vs 90 (Durometer): This is the hardness. 90 is harder/stiffer (often used for high-pressure tank valves), while 70 is softer and more flexible (common for dynamic seals).
