This Fluorosilicone 70A O-Ring, item FS70344, is designed for buyers who need a clear specification match for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-344; 3.85 inch (97.79 mm) ID x 0.21 inch (5.33 mm) CS; 4.27 inch (108.46 mm) OD, with 3 7/8 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. Its Fluorosilicone material provides 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. 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.
