1MM CS X 12MM ID BLACK EPDM 70D

Ordered as E1X12, this is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 12 mm (0.472 in), a cross section of 1 mm (0.039 in), and an outside diameter of 14 mm (0.55 in). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists ozone, UV and weathering, dilute acids and alkalis, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers strong performance in outdoor and exposed installations, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Applications involving mineral oil-based lubricants or petroleum oils and fuels call for a different compound.

Maintenance and OEM teams specify it across brake and phosphate ester systems, water and steam systems, and outdoor equipment.

Order part number E1X12, sold individually. Unit weight is approximately 0.043 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
