Recommendations For Alternative Fuels
Dixon has completed several years of testing and engineering evaluation to ensure our products are compatible with all
modern motor fuels in use today.
Dixon uses a proprietary seal compound that we refer to by the trade name Baylast™. Baylast™ has been tested both in the
lab and field with excellent results. Baylast™ was developed so we could offer a single seal material compatible with the wide
range of alternative fuels used today. Many Dixon Bayco products have been using Baylast™ seals to ensure compatibility with
alternate fuels including E100 Ethanol, E85 Ethanol, B2 Bio diesel, B20 Bio diesel, Ultra Low Sulfur Diesel, and standard refined
gasoline and diesel products with excellent results. Our tests indicate that Baylast™ performs well down to -40°F.
There are mechanical and temperature considerations that must be understood to determine which seal material is suitable for a
specific application. A good example is PTFE, it has a very wide chemical compatibility range but is a poor seal material for
mechanical reasons. Using Viton® B, or Viton® GF is one solution to ensure compatibility, but Viton® has limitations regarding
mechanical suitability for seal applications with moving joints. One critical and well known limitation to Viton® is cold
temperature. Viton® will become hard at low temperatures and seals with moving parts tend to weep liquid.
On the opposing page is our fuel compatibility chart which outlines our recommendation for each Dixon Bayco product and type
of fuel.
