An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

That behavior comes from the compound itself: EPDM (EPR) is known for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C).
You will find this material specified across HVAC and refrigeration, brake and phosphate ester systems, and potable water applications.
This item is sold individually under part number E70028. Unit weight is approximately 0.325 g and nominal inside diameter is listed as 1 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
