568-129 SILICONE O RINGS

Item S70129 is a Silicone 70A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-129; 1.549 inch (39.34 mm) ID x 0.103 inch (2.62 mm) CS; 1.755 inch (44.58 mm) OD, with 1 9/16 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. 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 red color and round profile provide a practical visual identifier during receiving, stocking and installation. This standard industrial O-ring can be used across compatible static and dynamic sealing applications in pumps, valves, cylinders and assemblies. 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.
