568-343 EPR 80 O RINGS PEROXIDE CURED

Use item E80PC343 when an EPDM 80A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-343; 3.725 inch (94.62 mm) ID x 0.21 inch (5.33 mm) CS; 4.145 inch (105.28 mm) OD, with 3 3/4 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The EPDM (EPR) construction supports 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. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
