Ordered as TFE315, this is an AS568-315 white PTFE (Teflon) 55 Shore D O-Ring supplied with an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The material holds up against oxidizing media, strong acids and bases, and steam. PTFE (Teflon) is valued for a very wide continuous service temperature range and near-universal chemical inertness. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C). Verify compatibility before use with molten alkali metals or elemental fluorine at temperature.
Maintenance and OEM teams specify it across food and beverage, laboratory equipment, and pharmaceutical and biotech.
This item is sold individually under part number TFE315. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
