The E2X16 is a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 16 mm (0.63 in), a cross section of 2 mm (0.079 in), and an outside diameter of 20 mm (0.79 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists water and steam, brake fluid, and dilute acids and alkalis. That behavior comes from the compound itself: EPDM (EPR) is valued for very good flexibility at low temperature and good electrical insulating characteristics. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with aromatic hydrocarbons or petroleum oils and fuels.
Common environments for this compound include solar and roofing assemblies, water and steam systems, and HVAC and refrigeration.
Reference part number E2X16 when ordering; the item is sold individually. Unit weight is approximately 0.208 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
