China, land of incorrectly sized garbage.

The standard sizes used by Parco and the other major O-ring manufacturers in the United States are defined by Aerospace Standard AS568B, Aerospace Size Standard for O-rings. That document, published by the Society of Automotive Engineers (SAE), lists the sizes of O-rings in six series or groups in both inches and millimeters. The first five series are based on cross-sectional diameter. The sixth series includes 20 sizes for boss seals. The standard sizes are also used for most military specifications

Durometer rating of orings? I'm looking to use this for high pressure supply line for power steering. thanks!

As long as the O-ring diameter is correct there shouldn’t be a problem.
