■ Product content and main applications

Product content
VALFLON is machined into a ring shape with a V-shaped cross section. Three shapes are available: for low pressure (L), for medium pressure (M) and for high pressure (H).
Main applications
It is used as a seal for pistons, rods, plungers, and valve systems for acid, alkali, solvents, oxygen, LNG, etc.
