.139" C/S (1/8" NOMINAL) (3.53 MM) epdm

This o-ring cord stock is supplied in black EPDM (EPR) 70 Shore A built to a cross section of 0.139 in (3.53 mm), catalogued under part number 0282139. It lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

EPDM (EPR) is known for strong performance in outdoor and exposed installations, excellent hot water and steam resistance. Expect good resistance to brake fluid, phosphate ester hydraulic fluids, and water and steam. It is not the right choice where mineral oil-based lubricants or petroleum oils and fuels are present.

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

This item is sold by the foot under part number 0282139. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
