Ordered as TFE213, this is an AS568-213 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 0.921 in (23.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.199 in (30.45 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, PTFE (Teflon) delivers near-universal chemical inertness and excellent dielectric properties. It resists solvents, oxidizing media, and strong acids and bases. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. It is not the right choice where molten alkali metals or service requiring elastic recovery are present.
Typical settings include semiconductor fabrication, food and beverage, and chemical processing.
Order part number TFE213, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
