362 PTFE SOLID BACKUP RING FDA

Ordered as TST362SO, this is an AS568-362 white PTFE (Teflon) 55 Shore D Back-Up Ring measuring an inside diameter of 6.225 in (158.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.645 in (168.78 mm). The back-up ring bridges the extrusion gap so the primary seal holds its shape under load.

PTFE (Teflon) is specified here for non-stick, non-contaminating surface characteristics and excellent dielectric properties. The compound resists steam, nearly all industrial chemicals, and oxidizing media. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C).

Maintenance and OEM teams specify it across pharmaceutical and biotech, laboratory equipment, and chemical processing.

Stocked as TST362SO and sold individually. Nominal inside diameter is listed as 6 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
