Genuine Bosch High Pressure Connector/Crossover Tube O-Ring, 2003-2018 5.9L/6.7L Cummins (Set Of 6)

Genuine Bosch High Pressure Connector/Crossover Tube O-Ring for 2003-2018 5.9L/6.7L Cummins. This is the same exact part you would get from a Cummins and/or Mopar dealership. These are sold as a set of 6!

This O-Ring seal is intalled onto the high pressure connector/crossover tube. We recommend replacing this o-ring seal any time the crossover tube is removed to ensure a proper seal when re-installed. A small amount of engine oil or engine assembly lube should be applied to the o-ring to prevent any tears or cuts to the o-ring during installation.
