The attached nut immediately rusts.
I can not find a substitute same rust-free nut.
Although there is no problem in use, it is unfortunate that only the nut rusts immediately although the main body does not rust.
I should have made similar products of other companies.
Creation of carbonated water

Used in conjunction with CPPE 7 - 6. It is very easy to use detachable with one hand. When plug is removed, pressure inside PET bottle can be kept, but when connecting plug, content may flow back into hose as you shake PET bottle, so if you use properly as check valve etc. depending on contents to be carbonated Is good.
