568-429 EPR 70 O RINGS

Item E70429 is an EPDM 70A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-429; 4.975 inch (126.37 mm) ID x 0.275 inch (6.99 mm) CS; 5.525 inch (140.34 mm) OD, with 5 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. The EPDM (EPR) compound is selected for water, steam, weathering and outdoor sealing applications where petroleum oil exposure is not the primary requirement. It is with a listed temperature range of -65°F (-53.9°C) to 300°F (149°C), which can help narrow material selection for heat, cold or process exposure. The black color and round profile provide a practical visual identifier during receiving, stocking and installation. This standard industrial O-ring can be used across compatible static and dynamic sealing applications in pumps, valves, cylinders and assemblies. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
