This o-ring is supplied in black EPDM (EPR) 70 Shore A built to an inside diameter of 479.3 mm (18.87 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 490.7 mm (19.32 in), catalogued under part number E5.7X479.3. It creates a positive seal at flange, piston and rod interfaces without added hardware. Source specification: Metric O-RING, JIS G480.

The material holds up against dilute acids and alkalis, ozone, UV and weathering, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) offers very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Applications involving mineral oil-based lubricants or aromatic hydrocarbons call for a different compound.

Typical settings include water and steam systems, solar and roofing assemblies, and outdoor equipment.

This item is sold individually under part number E5.7X479.3. Review your operating media and conditions against this specification before installation.
