-256 RED SILICONE 70D O-RING

This Silicone 70A O-Ring, item S70256, is designed for buyers who need a clear specification match for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-256; 5.734 inch (145.64 mm) ID x 0.139 inch (3.53 mm) CS; 6.012 inch (152.7 mm) OD, with 5 3/4 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. 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 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. 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.
