I bought a new multi-turn valve to replace a really old one.

enter image description here

The new one has a compression fitting where the old one is soldered. My plan is to use a pipe cutter just below the soldered joint. I'm not soldering or using sharkbite hardware. Here's a pic:

Do I need to prepare the surface of the pipe where the new compression fitting will be sitting to avoid a leak?

    I would heartily recommend returning that (new multi-turn) and getting a 1/4 turn shutoff - they are very good for the job and have far fewer problems from old age.

Generally speaking, the ring compression should work just fine. They don't look it, but they were standard long before the push-fittings came along and made this stupid easy. As long as there's nothing under the ring, it should seal properly.

I would get a wheel-type cutter to do this, however. Not only will it not burr the pipe, but it won't bend it either.
