O-rings are normally available with a hardness rating, as measured by an ASTM type-A durometer, of 70 (the "soft" kind) or more rarely a rating of 90 (the "stiff" kind). The soft O-rings are appropriate for dynamic applications where the O-ring is providing a seal with a constantly moving part, such as inside regulators. The stiff O-rings are more durable in static applications where the O-ring is providing a seal with stationary or occasionally moving parts, such as a valve.

The M26x2 outlet is similar in appearance but slightly larger than the standard DIN outlet, and thus incompatible with the standard DIN connector found on SCUBA regulators. The purpose of this incompatible valve outlet is to force the dedication of cylinders, regulators and fill stations to Nitrox use. The sealing O-ring in the nose of the M26x2 connector is 13.9 X 2.6 metric dimensions, equivalent to the 113 size. The M26x2 outlet and connector for Nitrox and oxygen is very rarely seen outside the EU.

General-purpose grease lubricants: General-purpose grease lubricant is excellent for o-ring and elastomer seal varieties used in hydrocarbon service. General-purpose grease lubricant has a recommended service temperature of -29 𐩑C - 82 𐩑C (-20 𐩑F - 180 𐩑F).Figure 5: O-ring measurement: Inner diameter (A), outer diameter (B), and cross-section (C) Determining o-ring material
