3X39 SILICONE 70 METRIC ORING

This Silicone 70A Metric O-Ring, item S3X39, 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 39 mm (1.535 inch) ID x 3 mm (0.118 inch) CS; 45 mm (1.77 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. Its Silicone material provides flexibility across broad temperature swings and clean sealing applications that require a soft, compliant elastomer. It is with a listed temperature range of -80°F (-62.2°C) to 450°F (232°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.
