Part number TFE041 is an AS568-041 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 2.989 in (75.92 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.129 in (79.48 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, PTFE (Teflon) is widely chosen for a very wide continuous service temperature range and near-universal chemical inertness. The material holds up against steam, oxidizing media, and nearly all industrial chemicals. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C). Verify compatibility before use with elemental fluorine at temperature or molten alkali metals.
You will find this material specified across pharmaceutical and biotech, food and beverage, and semiconductor fabrication.
Reference part number TFE041 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
