This o-ring is supplied in AS568-448 white PTFE (Teflon) 55 Shore D with an inside diameter of 9.475 in (240.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 10.025 in (254.64 mm), catalogued under part number TFE448. It delivers dependable bidirectional sealing in a compact groove envelope.
It resists solvents, oxidizing media, and steam. That behavior comes from the compound itself: PTFE (Teflon) is widely chosen for a very wide continuous service temperature range and non-stick, non-contaminating surface characteristics. Service temperature is rated from -65°F (-53.9°C) through 500°F (260°C). Verify compatibility before use with molten alkali metals or service requiring elastic recovery.
You will find this material specified across chemical processing, pharmaceutical and biotech, and food and beverage.
Stocked as TFE448 and 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.
