The different color orings are different types of materials. Certain ones had advantages over others. This quote off Guzzle's page is an example of the different material types he offers for fuel bowl drains.
Differences between the black Viton or the Blue Fluorosilicone fuel drain o-rings sold on this page:
* The black Viton o-rings are polymerized from two monomers, vinylidene fluoride and hexafluoropropylene (Viton type A).
* The brown Viton o-rings (Viton type B)are polymerized from three monomers, vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene. The terpolymer blend of Viton has shown to have additional resistance to fuel permeation ans swell when used with ULSD and BioDiesel than standard Viton (A).
* The Blue Fluorosilicone has a much wider temperature range than Viton (A) or Viton (B) and is widely used in extream environmental conditions. They will stay flexible in artic conditions down to -70º F.
Right now looking for orings for locking hubs. Maybe I will pick up some extras. Which one are good to keep on hand ?
I got the "mechanics parts cabinet" set. It has orings for the HPOP, turbo, fuel system, and EBPV. They already came in handy for my brother when one of the trucks they were working on was down and nobody had the gaskets for the fuel rails in stock. Best bang for your buck.
