CCV Vent Cover O-rings
4 Viton replacement o-rings for the Crankcase Vent cap on the top of the left valve cover.
Order of 1 is a set of 4 o-rings.
The doghouse bolt o-rings are a harder, durometer 90 Viton o-ring to keep the o-ring from tearing when tightening the doghouse down along with greater strength to resist the corrosive agents found in the crankcase gases.

As Expected
When you need new o-rings, you just want them to fit perfect and perform. While I haven't had them installed long enough to know for sure if they will last, the sure do fit perfect. Thanks!

Just installed, time will tell.
Just installed these o-rigs on my '02 7.3.
Time will tell if these hold up as well or better than factory o-rings.
They installed well and felt like they made a positive seal. -
Great O-rings
Work well for this.

Fit perfectly
I did a CCV mod and used these when reinstalling the doghouse. I have not had any oil or fume leaks from them.
