Product Specification

-
Ordered as TFE154, this is an AS568-154 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

PTFE (Teflon) delivers a very wide continuous service temperature range and near-universal chemical inertness. It resists steam, strong acids and bases, and nearly all industrial chemicals. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C). It should not be specified for service in elemental fluorine at temperature or service requiring elastic recovery.

Maintenance and OEM teams specify it across semiconductor fabrication, chemical processing, and pharmaceutical and biotech.

This item is sold individually under part number TFE154. Application requirements vary, so validate compatibility with your process conditions prior to installation.
