fixed, disregard post, thanks how to remove crimp?

If that is the "ear" i am thinking about, a good set of side cutters or wire cutters on the ear does it for me.

A small hose clamp works best for something you might remove, but, I don't view is as permanent connection.

A pair of Dikes (large wire cutters) cuts the crimp off at the Knuckle (ear). There are several types of bands, the one I found at ACE has a ratchet type of crimp. the other is just a bending ring, I suppose the plain bending ring would be the easiest to cut off with cutters.

I have clipped those with wire cutters but they can be a lil bit stiff. Be aware there are a couple of pipe types from that era that vary slightly on thicknesses.

The original Oetiker clamps have an interlocking end that you can pry off, or just cut the dimple. I really like this type of clamp- one size crimper fits all, the crimper is small and inexpensive, and the have a bit of spring tension to deal with expanding and contracting fittings.

thanks!!!! so replacing with a pex band is not an option? i should use the oetiker i guess

I never knew the name of that type of clamp. First saw them on CV Boots in FWD cars. Found I could cut or spread the old clamp and crimp a new one with a dull pair of diagonal wire cutting pliers. Later bought a Lisle tool meant to pinch that dimpled bulge to tighten them. Just saw a $9 tool on Advance Auto Parts. Size could be a problem, the automotive tools being too big. For RV, we need something that'll do a good job in a small space. I wonder if the Big Boxes carry those?

The Knipex pincers are good. The one with both front and side jaws offers more flexibility in tight spaces.

my crimp does not look quite like that, there is no adjustment or bumps or dimples. i would post a picture but no matter how small i crop the photo it is still to big

You probably have the "official" PEX crimps. It's very common to see Oetiker clamps used instead, and they work just as well.

To remove a PEX ring, I'd get out the Dremel with a cutoff wheel and go slowly to avoid cutting into or melting the tubing. They do make a tool, but it's expensive and you have to cut the tubing and lose an inch of length.
