16 Total O-rings

Now the other guy sent out Buna-n o rings, they don't have the resistance that Viton has. See the chart below:

The factory o-rings are Buna-Nitrile. Replace them with our Viton O-Rings. Viton will hold up to Bio-Diesel and ULSD. Each kit includes Sixteen (16) o-rings are made from high quality Viton® and are the same hardness as the OEM kit. 

 Viton is a registered trademark of DuPont Performance Elastomer's. 

This kit contains 16 black or brown viton O-rings - color has nothing to do with what its made of, Viton is stronger and more resistant to chemicals. Someone who is selling o rings that are brown and calling them viton is mistaken, any type of o ring can be sold in any color, so color is not a trade of Viton!

84-94 Ford F-series diesel engines.

All sets will be shipped the next business day after payment.
