Needle valve sticking solution By Regulator on 2/21/14
Regulator would recommend this product to a friend
This is actually a great product contrary to the first review. I have been using mine for over a year now and I bought it used. Naturally CO2 is corrosive so the needle valve may get suck in the open position over time. There is a simple solution to this, disassemble the needle valve housing and apply a couple drops of vegetable oil around the seat of the needle and on the needle it's self. ( I called the manufacturer and this is what they told me.) WARNING: DO NOT USE PETROLEUM BASED OIL. I have not had any problems since doing this.
