568-278 CHLOROPRENE 70 ORINGS

Use item N70278 when a Neoprene 70A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-278; 11.984 inch (304.39 mm) ID x 0.139 inch (3.53 mm) CS; 12.262 inch (311.45 mm) OD, with 12 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The neoprene (chloroprene) construction supports moderate oil resistance, ozone resistance and weathering performance in general-purpose industrial service. It is with a listed temperature range of -40°F (-40°C) to 250°F (121°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.
