Help To change barrel o-ring Fx impact

[diabolix]

I have an impact since 2 months and unfortunately the barrel o-ring is going out.
I tried several time (2/3 hours)To put à new one without success.
I bought some specific tools for o'ring but without success, I already desroyed 4 new o'ring.
Could you help me ? Is there a specific tool or method To put the o'ring inside the barrel?
I am desesperate.

Run a quarter inch wood dowel down the barrel and it holds the o ring in place while you install it.

I'll second that ... just put the dowel rod just above the grove and push in with your finger after throwing some silicon grease on it. Once it is in there and not folded over you can do a little last minute positioning with a tooth pick or dental pick. It used to be an exercise in frustration trying to get the darn thing positioned correctly without folding over on itself ... now it takes less than 2 minutes and it's done.

Come to think of it, I think I was using a 3/16 inch dowel rod, didn't want to take the chance of it getting stuck in there ... but 3/16" worked just fine.

I used a cleaning rod from one of my rim fire rifles I wrapped masking tape around tip to create a dam to keep oring from getting hung up remember to use a bit of silicone on the ring.

Not to worry ... this will work. You didn't say what caliber you have but the 3/16th inch dowel rod will work for the .22 and you might get by with the 1/4 inch with the .25

​I wouldn't even attempt it anymore without a dowel rod ... make sure it is at least a foot longer than the barrel and moderator of your longest gun so you can use the same dowel on all of your guns.. They also work great if you want to push a pellet through your barrel to check out the engraving of the pellet by your barrel ... or if you have a pellet stuck inside the gun ... like if you accidentally double loaded the barrel.

I purchased some brass rod from McMaster-Carr which is slightly smaller than bore diameter. Insert the rod to a position just behind the barrel O-ring groove. Insert the new Oring into the barrel and gently work it into place with the aid of a plastic dental pick.
At first it appears to be an insurmountable task but once you learn how to do it one can be replaced in minutes.

If manufacturers designed for the O-ring seal to be on the pellet probe instead of the barrel it would make things much easier. I blew a Bantam O-ring yesterday; they too can be difficult.
