Gas Tube Wrench

Well worth the money. Have used twice already to remove carbon stuck gas tube without damage to tube. Grips well and makes breaking loose from carbon a breeze.

Did the job

I had a gas tube that was extremely difficult but this tool helped me get it. I had to use an upper receiver clamp in the vice and hammer on the stem of the tool near the clamping end, but it came off. I dont think I could have got the tube out without this tool. Plus I have the proper tool for the job now.

Great tool!

I got tired of tearing up gas tubes and gave this tool a try. It grabs tight while not harming the tube. Makes removal and assembly very easy. Worth then investment as far as I'm concerned.

Yes, you do need it.

This is one of those tools we have all looked at and said "Looks useful, but I'll just keep using my old pliers". I did for a couple of years and got tired of chewing up gas tubes. This wrench is the best for removing even the most stubborn carbon caked tubes. Super easy to use. Glad I took the plunge and got the right tool.
