**3MM C/S X 440 MM ID

Item V3X440 is a FKM Viton 75A Metric O-Ring built for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 440 mm (17.323 inch) ID x 3 mm (0.118 inch) CS; 446 mm (17.56 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. 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. 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. 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.
