Rubber O-rings

EPDM is a synthetic rubber which is UV resistant.
The glow in the dark o-rings are made from silicone and are UV resistant. They are charged by full spectrum light.
The Link It! o-rings are made from a non-latex synthetic rubber called nitrile acrylonitrile.

The ring measurements are nominal rounded values. Slight variations may occur. Our code numbers provide a guide to ring size.

id = inner diameter.
od = outer diameter
AR = Aspect ratio. This is the ratio of the inner diameter to the rubber thickness (id/rubber diameter)
AWG = American wire gauge. The gauge is quoted in American Wire Gauge (AWG) as so many patterns originate from the USA.
