If you have an aftermarket oil bypass kit with a return line feeding back into the engine oil fill cap, chances are, you get tired of removing this line to remove the oil fill cap! We designed our swivel oil fill cap to eliminate this issue. With our swivel fill cap, the line stays connected, and you can remove the oil fill cap without the hassle and the mess! This fill cap is designed to work with the factory Plastic Cummins valve cover. It has a 1/8 NPT return port on a swivel, so no more return hoses getting pinched or sharp bends! Designed to work on all 2006 and newer Cummins factory valve covers!
Made using all aluminum and stainless materials, proudly right here in the USA!
