4MM CS X 122MM ID BLACK EPDM 70D

This o-ring is supplied in black EPDM (EPR) 70 Shore A built to an inside diameter of 122 mm (4.803 in), a cross section of 4 mm (0.157 in), and an outside diameter of 130 mm (5.12 in), catalogued under part number E4X122. It delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against ozone, UV and weathering, water and steam, and ketones. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for good electrical insulating characteristics, outstanding weather, ozone and sunlight resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Exposure to petroleum oils and fuels or aromatic hydrocarbons will shorten service life.

Typical settings include water and steam systems, outdoor equipment, and HVAC and refrigeration.

Reference part number E4X122 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
