Part number TES70423 is an AS568-423 red PTFE-Encapsulated Silicone 70 Shore A O-Ring measuring an inside diameter of 4.225 in (107.32 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.775 in (121.29 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as ORING 70 Durometer.
The compound resists strong acids and solvents, wide temperature swings, and steam. That behavior comes from the compound itself: PTFE-Encapsulated Silicone offers strong resistance to permeation and a non-contaminating, non-stick sealing surface. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.
Typical settings include pharmaceutical manufacturing, cryogenic and high-temperature equipment, and food and beverage processing.
Order part number TES70423, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
