*EPDM ORING 3 MM X 39 MM ID X 45 MM OD

This EPDM 70A Metric O-Ring, item E3X39, is designed for buyers who need a clear specification match for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 39 mm (1.535 inch) ID x 3 mm (0.118 inch) CS; 45 mm (1.77 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. Its EPDM (EPR) material provides 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. Metric sizing supports imported equipment, metric gland designs and replacement work where inch-series AS568 dimensions do not apply. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
