Worked for me on the 3/4" size tube
The outside diameter of the 1/2" section is approximately 1/2".
Bill, It is .485. That is .015 < 1/2 inch. I used it to re-round the floor lines going into the copper manifolds. I trimmed the pex tube to length, slipped a 1/2" cinch ring on the tube and used tool to open and round the pex tube. The tube slipped on the manifold barb very easily all the way and the cinch ring crimped very easily and no leaks. Oh, this was for radiant heat in concrete floor. Hope this helps. Be sure to cut the lines slightly long so they push against the manifold while crimping. I also flushed the lines with house water pressure and got the air out and shut the valves after connecting to manifolds, both in and out sides. Lines had water and no air in them. Roger
The OD is 1/2-inch. The tool is used to de-burr (and chamfer) the inner and outer edges of typical 1/2-inch PEX-AL-PEX tube; for preparation of the fitting. (And, it does a nice job). All standard 1/2-inch PEX-AL-PEX tube (which I've worked with) has 1/2-inch ID. The tool's 1/2-inch nipple fits snugly into the 1/2-inch tube. It does not deform the tube. After insertion and rotation, the tool's metal blade makes a very small cut (chamfer) simultaneously on inner and outer edges.
This tool only bevels the inside of PEX-AL-PEX tubing.
This tool reams the inside of PEX-AL-PEX to make a beveled edge so that the o-ring on the fitting can set properly.
