Aflas® O-Rings

Aflas® (TFE Propylene)

Trade Name:
Above ..................................................3M

Aflas, a recently introduced material, is unique due to its resistance to petroleum products, steam, phosphate esters and brake fluids.  In some respects it exhibits media compatibility properties similar to ethylene propylene and fluorocarbon. It has fair resistance to brake fluids and phosphate esters while exhibiting good resistance to petroleum oils. Aflas is finding interest for seal applications requiring petroleum resistance, steam and amine resistance such as those applications encountered in the petroleum industry.  Aflas o-rings are great in applications requiring petroleum and brake fluid resistance or petroleum and phosphate ester resistance.  The temperature service range for this material is -20oF to
+446 oF.
