568-166 BLACK FKM 75 DUROMETER O-RING

Item V75166 is a FKM Viton 75A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-166; 6.737 inch (171.12 mm) ID x 0.103 inch (2.62 mm) CS; 6.943 inch (176.35 mm) OD, with 6 3/4 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. The FKM/Viton fluoroelastomer compound is selected for high-temperature service, fuels, lubricants and many chemical sealing environments. It is with a listed temperature range of -15°F (-26°C) to 400°F (204°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.
