568-417 PTFE ORINGS FDA

APG stocks the TFE417, an AS568-417 white PTFE (Teflon) 55 Shore D O-Ring with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists nearly all industrial chemicals, strong acids and bases, and oxidizing media. That behavior comes from the compound itself: PTFE (Teflon) is specified for near-universal chemical inertness and non-stick, non-contaminating surface characteristics. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service.

You will find this material specified across laboratory equipment, aggressive-media pipelines, and pharmaceutical and biotech.

TFE417 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
