| ASTM test references | ASTM D4894, ASTM D4745 |
Final dimensions, tolerances and material grade are confirmed against your drawing and service conditions.
Applications & selection
Typical uses
- Isolation duty
- Corrosive media handling
Industries: Chemical, Pharmaceutical.
Selecting the right construction
Specify nominal bore, flange standard, actuation and pressure-temperature duty. Confirm lining material and required inspection records; body class is not the assembly's operating pressure.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
