Want to sell a new SS 1/8" Parker 2F-C4L 6000# check valve with two genuine Foster male quick connects to use between your compressor and tank during filling. With this check valve inline you can fully open your tank and then turn on your compressor without having to watch the compressor come up to the tank pressure then opening your tank valve. It will also hold your tank pressure in the event of a leak up stream of the check valve during the fill process. $85 PP F&F shipped. Contact me via PM.
