568-134 PTFE ORINGS FDA

TFE134 is an AS568-134 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

PTFE (Teflon) is known for near-universal chemical inertness and one of the lowest coefficients of friction of any solid. This material stands up to steam, 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. Applications involving molten alkali metals or elemental fluorine at temperature call for a different compound.

Maintenance and OEM teams specify it across pharmaceutical and biotech, food and beverage, and aggressive-media pipelines.

Order part number TFE134, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
