**568-248 FLUOROSILICONE 70 DUROORING

Item FS70248 is a Fluorosilicone 70A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-248; 4.734 inch (120.24 mm) ID x 0.139 inch (3.53 mm) CS; 5.012 inch (127.3 mm) OD, with 4 3/4 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The Fluorosilicone compound is selected for fuel and oil resistance paired with low-temperature flexibility for specialty sealing service. It is with a listed temperature range of -80°F (-62.2°C) to 350°F (177°C), which can help narrow material selection for heat, cold or process exposure. The blue 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.
