I have 4 gc extreme valves for sale as I just went to new smc 3/8 on the front of my truck. Had em on for a year with no issues. These are way fast. Asking $125 for valves setup with all fittings seen in pic. Price is firm as that is a steal. I also have a bunch of extra 1/2 fittings as well as flow controlls for these as well.Will post pics of fittings soon. Thanks for looking.
I think they'll fit in a flat rate box. Maybe $10 more. Forgot to mention one valve electrical connector is cracked. You can see a ziptie around it in pic. Doesent affect anything though. I got it that way when it was new, didn't bother me enough to return it.
