My Paasche D-500 came equipped with a Badger regulator/moisture trap that shows pressure to 160 psi. I would like an air pressure gauge thatshows pressure to 60 psi since the compressor's maximum is 28 psi. I think that would be easier to set than the 160 psi gauge. I have Googled for an hour and cannot find one. Anyone have a suggestion? Both the Paasche and Badger sites show their regulators with this gauge but no separate part numbers. What type of local supplier might carry this? Auto parts? Home Depot? Michaels?
