*1.995 X 2.223 X 0.054 PTFE SPLIT B/U

Part number TST1.995X2.223X.054 is a white PTFE (Teflon) 55 Shore D Back-Up Ring supplied with an inside diameter of 2.22 mm (0.087 in), a cross section of 2 mm (0.079 in), and an outside diameter of 6.22 mm (0.24 in). A back-up ring allows a standard o-ring to operate at higher pressures than it could unsupported. Supplementary detail from the product record: Tol +/-0.005 ON Diameters.

PTFE (Teflon) is specified here for non-stick, non-contaminating surface characteristics and excellent dielectric properties. This material stands up to strong acids and bases, oxidizing media, and nearly all industrial chemicals. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C).

Typical settings include semiconductor fabrication, laboratory equipment, and food and beverage.

TST1.995X2.223X.054 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
