It was well packed up with bubble wrap like 8 wraps. Came snug in well taped perfect box size and I had my 5 yr old yong heng 100% completely rebiult and running like a little beast.I tried the pcp compressor out with the new upper stage piston head on my AEA pro .22 with a 350cc tank from 170 bar to 300 bar 2 minutes and 22 seconds. It is now my back up compressor. My yong heng only needed a new rd flat dime sized check valve/ there prone to snap/no money in that.
