1 MM C/S X 9 MM ID

Use item S1X9 when a Silicone 70A Metric O-Ring is required for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 9 mm (0.354 inch) ID x 1 mm (0.039 inch) CS; 11 mm (0.43 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. The Silicone construction supports 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. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
