fixed, disregard post, thanks how to remove crimp?

[rockwind1]

so have a 2007 attitude toyhauler. 2 different crimps (toilet supply and hot water to showerhead) are leaking so i need to re crimp the pipe i guess. any thoughts, i have normal crimping tool for regular house plumbing, for Pex pipe. the crimps are different though. the metal crimp on the trailer has a "ear" on it, kind of leftover metal after they crimped it

what is best way to remove crimp?

[rockwind1]

fixed that sucker, thanks for the help. they have these new screw on deals so no more crimping. piece of cake

I bought a ratcheting tool from Lowes for around $40- it works great for crimping but doesn't remove. It's a LOT handier than the pex crimp tool I have.

FWIW, I use a dremel or plain hacksaw on the pex rings- but cut diagonally, and don't go all the way through, rather cut a deep slot and pop it open with a flat screwdriver. You don't risk damage to the tubing this way.

^^^ shows "unavailable"

Wanted to mention there are plastic probably PVC or CPVC versions of the metal Shark Bite fittings. Might be nicer for PEX.

so posted a youtube video on my sons accounts of the crimp and stuff. if anyone wouldn't mind taking a quick view, it is kind of

shaky at the end.

PEX Bands, Yeeks! Gonna be Oetiker or SharkBite for me if I have to get to those.

Do most of the Oetiker Crimp Pliers cut as well as crimp?

This automtive version looks like my Lisle tool. It doesn't cut an old clamp away. Only crimps the new one. Hard to see from a photo, but it has a little anvil above the pivot pin. That keeps the part you crimp, from folding into a peak instead of collapsing from the two sides.

I might cut the PEX band with a Dremel tool, then crimp Oetiker clamps with my Lisle.

Sharkbite connectors also work on PEX, and might be an easy reassembly option if there's enough room.

I used pex 'rings' on my RV as that's what it came with from the factory, just like at home.

If you have enough slack, cut the pipe and clamp off as the leak could be from the pipe, not a loose crimp.

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.

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

[mike-s]

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

...original Oetiker clamps...

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

[Chris_Bryant]

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.
