If you want a kit that includes the 8 O-Rings & the Tool, Check out my Other Items
This listing is for a harder and more durable O-Ring that will withstand higher temperatures and pressures over time. If you want a lasting solution you need the upgraded rings! This is not a seal you want to go cheap on.
Between myself and everyone that have used these rings we have hundreds of thousands of miles on many trucks.
If your nipple cups/ball tubes are badly worn, they should be replaced with the kits from Bostech. Otherwise a light polish is sufficient (see videos below for complete polishing instructions).
Nipple Cups/Ball Tubes are Not Included
High Pressure Oil Rail is Not Included
A Special Tool is Required to Replace These O-Rings. This Tool is Not Included but available in my other listings or for added cost.
I do have the tool available for sale for an extra $55. This is a tool custom made for me by HH Diesel and is superior to the Bostech tool.
For the complete story and instructions on replacing these seals follow the thread on The FTE forum:
Here are my personal videos on this problem and the solution:
No warranty on O-rings. They are guaranteed to be good, new, quality O-rings.You will get 8 brand new O-Rings to replace all 8 nipple cup seals.
