The part comes with 2 sets of O rings at two different sizes, brush, lube and a checkvalve.
The housing is the proper grade of aluminum and is coated on the inside and powdercoated on the outiside which is equivalent to the OEM specifications for color and durability. This coating provides a much better surface to resist galvanic and other corrosion. This is compatible with the cummins machined inserts from the old version (prior to MOTA change made by Cummins).
