The valve should be inserted in the other end, where the cartridges go. Why? Because all those slotted holes have sharp edges, and will damage the new O-ring.
It's a good idea to remove all the burrs and rough edges while you have it apart at this stage as well. These don't have the greatest finish to the milled/ processed edges. A little Emery and wet and dry goes a long way to making these little rifles a lot smoother.
could someone help me I have a problem because my rifle is leaking air from the part where a screw goes near the high screw that holds the wood Can someone tell me what I have to do since I have no idea what I should change If the screw or not I have an idea
so I use a qb79 and use the 88g bottle and recently its dumping all the co2 straight through the barrel.. would this be down to a seal problem on the valve.. any input would be appreciated 👍
Good chance it's the seal, but either way once you disassemble the rifle it will will become very obvious. Presuming you've had the rifle for a while probably a good idea to replace all the seals as routine maintenance. Good luck 🤞
hey, is there some picture or how is the valve attached to the valve tube? i know crosmans 22xx series need 2 pin it if u hpa it but im not sure how these qb:s valve can stay there without doing anything if u hpa it ??
When you tighten the valve the o-ring compresses which secures the valve to the tube - which is why you have to loosen it in order to remove. Hope that helps?
Interesting idea!
I have a qb78 and knew that you needed a special tool for the valve...
This is a very cheap & simple alternative!

Makes sense... Thanks for the tip! 👍

@@handlesarefeckinstupid Sage advice 👍
thank you for this video. do you have a link so i can order the complete set of orings?? or at least the valve orings needed to stop the leak? TY
Just cut down an old socket so there just two prongs left. Simple.
how do you remove the barrel from the Co2 tube

@@b1cates ohh i see, there is no any bolt to attach valve tru tube?
@@kawasaki5006 A bolt secures the brass section of the valve to the tube. The o-ring provides an air tight seal.
@@b1cates ohh thanks now i get it !
@@kawasaki5006 🙄🤣👍Good luck Bro👍👍
Co2 only leaks when my gun is cocked all the way forwards
That's because the the hammer is pressing against the valve stem. You must have had it apart and has been reassembled incorrectly.
