Structure:
Euroflex®-diagonal plaiting, “edge reinforced”
Form of delivery:
piece goods from 5 mm to 50 mm square
Media resistance:
Applicable against most media. Not applicable against
concentrated acids and alcaline-solutions,
few organic compounds, alkali metals, elementary
fluorine and fluorine compounds.
Notes:
“Edge reinforced” qualities are especially for
piston pumps. Through the aramide reinforcement
the extrusion of packing can be decreased. The PTFE
in the sliding surface makes ist possible to seal
