1X21 SILICONE 70 METRIC ORING

Item S1X21 is a Silicone 70A Metric O-Ring built for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 21 mm (0.827 inch) ID x 1 mm (0.039 inch) CS; 23 mm (0.91 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. The Silicone compound is selected for 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. 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.
