2.4MM CS X 4.3MM ID BLACK EPDM 70D

Ordered as E2.4X4.3, this is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 4.3 mm (0.169 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 9.1 mm (0.36 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to phosphate ester hydraulic fluids, ketones, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, strong performance in outdoor and exposed installations. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.

Maintenance and OEM teams specify it across HVAC and refrigeration, solar and roofing assemblies, and outdoor equipment.

E2.4X4.3 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
