Oxygen and Nitrox Compatibility – Important Notice

The polyurethane 90 Shore A compound used in our AS568-111 O-rings has been confirmed by Europe Seals as suitable for oxygen applications.

These O-rings may be used in compatible scuba equipment for air, Nitrox or oxygen-enriched breathing gas applications, provided the equipment manufacturer’s specifications and applicable oxygen-service requirements are met.

IMPORTANT: Scubagaskets O-rings are NOT supplied oxygen-clean or ready for oxygen service.

Before use in oxygen or oxygen-enriched breathing gas systems, O-rings must undergo appropriate oxygen-service cleaning, handling and inspection according to applicable procedures and equipment manufacturer requirements.
