2.5MM C/S X 128 MM ID

This FKM Viton 75A Metric O-Ring, item V2.5X128, is designed for buyers who need a clear specification match for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 128 mm (5.039 inch) ID x 2.5 mm (0.098 inch) CS; 133 mm (5.24 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. Its FKM/Viton fluoroelastomer material provides 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. 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.
