    What is the difference between the kopex pipeslice available on amazon etc and the kopex by JTM listed on the JTM plumbing website( Kopex) . On closer inspection on the picture has rothenberger on picture.

    Many people say kopex are the pipeslice to go for would you agree?

    I have recently bought the Regin ones after having happily used the Kopex ones for years but disliked the plastic 28mm ones. I am seriously impressed with them. Had them 6 months so far and no complaints all 3 of them 15, 22 & 28 are all metal and easy to maintain. A real contender to the Kopex. The choice is yours...

    I'm against the plastic one Shaun! I found the plastic 28mm wears out prematurely and only last about 6 month before its more of a threading tool than a cutter! But I do a lot of big bore pipework so maybe it's just me.

    Cheers for all your replies. I was thinking kopex is the one to go for, but unsure the one listed on the JTM plumbing site is kopex or rothenberger. Link posted in original post

    Confused? You will be, after another exciting episode of SOAP.

    I have a mix. Monument, rothy and my 28 is plastic. For the big stuff I prefer my ratchetting cutter I bought from HWOS.

    It was also weapon of choice in the secret santa

    Yeah it's a strange one, seen somewhere else aswell rothenberger by kopex similiar image. Maybe best to ask them, only thing is usually they are not sure themselves.

    I've got a plastic one in the workshop here and I won't buy another. As you say, in about six months of moderate use, the pins that go through the rollers wear in their fixing holes to make the hole out of round. Then the slice starts tracking up the pipe. One to be avoided unless you only use 28mm occasionally. I can see the value in it not corroding so easily in storage.

    Rotten burger is a kopex, Kopex did have a patent I think but with the amount of cheap copy's now I'm guessing it's up. Monuments are better then Kopex imp.
