Economy Barrel Cap Won't Seal

[springtime]

Just barreled my Wherry and looked at the rubber "O" ring on the cap.
It was a bit dented from the previous brew.
When I tried to seal it beer leaked out from the side of the cap.
After several tries with no success I shot down to the local brewing shop to get another rubber "O" ring.
To my surprise it would not seat in the cap propperly so I had to stretch it several times to make it fit.
The cap is now done up but to be honest I have no faith that it will seal properly.
It looks like it's time to ditch the economy and get another cornie.

I've had the same problem, and I know others have too. The lids/seals on the economy barrels seem to be the weak point.

I just bought another lid off eBay with a CO2 injector valve, now every time I fill it I give it a quick squirt of gas just to make sure it's sealed. I think I was doing the original one up way too tight and distorted/cross-threaded it. With a smear of vaseline and just hand-tight the new lid seals fine and has extended the life of the barrel.

Did you add petroleum jelly to the thread before you put the cap on?

Vaseline is the same thing :)

The keg I borrowed was covered in it and it worked like a charm :)

Haha yes you are very right but it's double to three times the price :p

I think you're right, I was doing it up too tight - here's hoping that the barrel keeps pressure.
