I have 2 co2 outlet valves, pretty much brand new, both need new orings but haven’t had more than 3 fill through them. I have 4 green gas outlet valves, same deal should put on new orings but no more than 2 fills on either. I also have 5 inlet ghk original green gas. Orings are all pretty good, no more than 2-3 fills on them. These are the remaining parts from a Devil hunter mod. I will not part out I want to sell the whole lot, that’s effectively the only economic way for me. PayPal is my preferred method to avoid hopup fees
