O-ring, FKM GF-600S 75A -3 AN, Brown

If you looking for an enhanced seal that can handle the most aggressive automotive fluids without breaking the bank, look no further. Viton™ GF-600S provides superior performance compared to standard Viton™ (FKM) and Buna-N (Nitrile/NBR) in almost all automotive applications. Viton™ GF-600S will reduce downtime and the worry for leaks caused by swelling and deterioration of the seal.

Viton™ GF-600S provides superior temperature range and chemical resistance with lubricating oil (SE, SF, SG, SH) aqueous fluids (water/coolant), mineral acids, aromatic hydrocarbons (Toluene/Xylene), automotive fuels (oxygenated with methanol, ethanol, MTBE, etc.), aviation fuel etc.

Racetronix stocks Viton™ GF-600S in all the most common AN sizes. They may be purchased individually or in packs.

Viton™ GF-600S seals should be considered as an upgrade especially in fuel systems using Methanol (methyl hydrate) or Ethanol (E85/E99). Viton™ GF-600S has a rating of ‘excellent’ for use with most automotive fuels.

Racetronix can provide custom sizes with MOQs as low as 200 pieces (size dependent)

The technical stuff:

Viton™ GF-600S is a fluoroelastomer gum manufactured using Advanced Polymer Architecture (APA) technology. Viton™ GF-600S contains 70% fluorine and is composed of hexafluoropropylene (HFP), vinylidene fluoride (VF2) and tetrafluoroethylene (TFE) with a peroxide cure site.

Features:

• Highly fluorinated
• High temperature resistance.
• Good resistance to steam and hot water
• Excellent resistance to acids, fuels, mineral oils, greases, aliphatic, aromatic and chlorinated hydrocarbons, nonflammable hydraulic fluids (HFD) and many organic solvents and chemicals.
• Excellent resistance to aging and ozone.
• Low gas permeability, low compression set.

Limitations:
• Amines, polar solvents, low molecular weight organic solvents and glycol-based brake fluids.
