Hi,
Anyone have a good method to grip metal pipe without marring?
I'm looking for a DIY method, hopefully with basic tools.
It's 1/4" zinc plated pipe and I have another 1/4" pipe with a smooth
finish(i think it's stainless). Both pipes have 1/4" MPTs and I'm
trying to fit some female fittings on the ends.

Also, if there is some special tool(reasonably priced I hope) that
would make thinks much easier, let me know. What do the pros use?

Thanks!

You've already had replies concerning strap wrenches and split wood
blocks.

Split wood or soft metal blocks held in a vise are a favorite of
gunsmiths for holding barrels without marring them. Powdered rosin
will make them even grippier, if you need it.

There is also a wrench called a girth wrench, made for plumbers for
doing the same thing. They are still made by Parmelee:

The jaws are wide, smooth three-piece jaws that completely circle the
pipe or bar. Each diameter requires its own set of jaws.
Unfortunately for you, they only go as small as 1/2" pipe. Plus, they
are expensive.
