cutting copper pipe for pushfit

[diyjunky]

I may need to cut piece of copper pipe with a multitool or Dremel that's in a difficult position.
I then want to use a *pushfit* coupler, either Techtite or John Guest.
Everybody says that you need to cut the pipe square - but I can't guarantee this.
Am I right in thinking that as long as the o-ring has sealed on the pipe, a small angle on the pipe up from it will not make any difference.

Am I missing something please ??

Small is ok, make sure the pipe is well rounded/filed.

A dremel will leave a very sharp edge and burr on the bottom half of the pipe, if curtting straight down and will rip the seal to bits. You need to cater for getting strip of emery/120 paper or a deburrer into the space and completely clean the end before you go anywhere near it with a pushfit fitting.

Thank you denso & Madrab, because of the awkward position, I can only file with small files and 300 grit paper. I would also apply silicone grease on the pipe for ease of fitting. I would ensure that it is very clean and smooth at the end.
Please feel free to suggest anything else I may have missed.

Unless you can get the cut edge completely smooth and rounded over You'll be better using compression fittings in you circumstance.

Is there not even enough room fro one of these https://www.screwfix.com/p/monument-tools-originals-15mm-automatic-copper-pipe-cutter/298pg once its on you only have to get a finger and thumb on it to turn it and only need a few mm at a time before you change your grip if space is tights

Dismantle the fitting, put the bits over the pipe carefully then screw it together, make sure you don't mix them up or get the grab ring the wrong way round.
