568-459 PTFE ORINGS FDA

Ordered as TFE459, this is an AS568-459 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 14.975 in (380.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.525 in (394.34 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

PTFE (Teflon) offers a very wide continuous service temperature range and excellent dielectric properties. It resists nearly all industrial chemicals, steam, and solvents. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service. Verify compatibility before use with elemental fluorine at temperature or molten alkali metals.

Typical settings include aggressive-media pipelines, pharmaceutical and biotech, and laboratory equipment.

TFE459 ships individually. Nominal inside diameter is listed as 15 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
