I need to go to lowes and get some spare puncture pin seals (the nylon washer that seats around the 12g puncture pin) for my phantom. Does anybody know what size they are so it doesn't take me forever to find one? I would just take one but I froze my last one so its too distorted to try and figure it out. If nothing else I can just take the whole air adaptor assembly with me and test fit. Thanks.
