Canadian Airgun Forum

Hi, Guys/ Gals. A few years ago I bought a "Smart Valve" it is suppose to fit Before the co2 bulk
canister I another brand before they are great for help, good in trouble shooting a leaky gun you have the ability
to shut the co2 off quick once you determine where the leak is not mention maybe it help`s keeping pressure off the air rifle Anyway when I was opening the new package and I know something fell out the only thing I could find was a small white oring I/d maybe less then 3/16ths I don't know for sure if that is what fell out but it dose look like it would fit around the small probe. Looking inside the opening for where you normally screw the bulk canister inside the qb79.
I looked all over there web site and cant find anything that screw in,in/off valve is an 1 inch a quart long, so must be discontinued or what ever I gave a lot of effort cant find it on the web at all so my question is do you know if that oring belongs to the "Smart valve" all it says is smart o parts under Smart valve the numbers on the card inside the box (with no instruction or parts list all there is the following, "842030" - pre-set Valve, after that number then "VLVSSAANY" "Made in USA" can any one help me? I have done the search on here as well! Very frustrating all 3 of my QB`s are leaking from some where they all sat for a year while I was sorting out my life and when I did get a short chance to shoot is was with my now stolen Drolov rifle oh that still stings, Would really appreciate the help! Please and thanks' YOU IN ADVANCE!
Scott

I believe that the small o-ring is a spare for the shaft of the knob you turn to open/close the co2.
