I have a Yeng Heng 4500psi compressor it works great with no problems, I used it as a backup for my Omega air charger and I recently got a Air Ventura compressor from a friend so I've decided to sell the Yong Heng it comes with extra orings, seals and burst disks comes with everything in the pictures and I just changed the oil. It also comes with a parts compressor I got from my friend. Asking $175 pickup in Kansas City, Mo only and that way I can show you it works just fine...Thanks Terry
