It creates a positive seal at flange, piston and rod interfaces without added hardware.
PTFE (Teflon) offers near-universal chemical inertness and a very wide continuous service temperature range. Expect good resistance to solvents, nearly all industrial chemicals, and oxidizing media. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C). Verify compatibility before use with service requiring elastic recovery or elemental fluorine at temperature.
Common environments for this compound include pharmaceutical and biotech, chemical processing, and semiconductor fabrication.
Reference part number TFE029 when ordering; the item is sold individually. Nominal inside diameter is listed as 1 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
