fixed, disregard post, thanks how to remove crimp?

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

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?

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

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.

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.

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.

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.
