The TFE472 is an AS568-472 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 23.49 in (596.65 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists steam, oxidizing media, and nearly all industrial chemicals. That behavior comes from the compound itself: PTFE (Teflon) delivers non-stick, non-contaminating surface characteristics and a very wide continuous service temperature range. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Applications involving service requiring elastic recovery or molten alkali metals call for a different compound.
Common environments for this compound include food and beverage, pharmaceutical and biotech, and laboratory equipment.
Order part number TFE472, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
