Review on Hot Max 24011 Flashback Arrestor by Austin Wolf

I did a bubble test after installation and got a lot of bubbles from the acetylene block. After removing it from the burner, I found that the sealing surface of this flame arrester was so poorly finished that it was impossible to tighten it sufficiently without leaking. The photo shows a ditch all over the face. I should have checked it out before I even tried it. Also, when I tried to remove the flame arrestor from the hose, the block inside detached and fell apart. It had both a flash suppressor and a one-way valve, but the editing was very poor. Returned on credit, bought a Hobart.
