Part number TSP013 is an AS568-013 white PTFE (Teflon) 55 Shore D Back-Up Ring supplied with an inside diameter of 0.426 in (10.82 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.566 in (14.38 mm). A back-up ring extends o-ring service life by supporting the seal against extrusion under high pressure.
The compound resists solvents, strong acids and bases, and steam. That behavior comes from the compound itself: PTFE (Teflon) is widely chosen for non-stick, non-contaminating surface characteristics and one of the lowest coefficients of friction of any solid. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C). Verify compatibility before use with elemental fluorine at temperature or service requiring elastic recovery.
You will find this material specified across pharmaceutical and biotech, semiconductor fabrication, and chemical processing.
This item is sold individually under part number TSP013. As always, verify media compatibility and operating conditions against the requirements of your specific application.
