568-201 SILICONE O RINGS

Use item S70201 when a Silicone 70A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-201; 0.171 inch (4.34 mm) ID x 0.139 inch (3.53 mm) CS; 0.449 inch (11.4 mm) OD, with 3/16 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. 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 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. 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.
