We need to do some simple hydrotesting of some new design refrigerant
piping and similar. The new refrigerants run up to 500 psi under certain
conditions, we would like to to 4x testing for safety ie 2000psi. This
is on the design side, looking for the obvious failures, will have the
whole thing tested by a lab when we are done.

At a previous place I worked we had a simple hand pump with a pressure
gage. It looked like a heavy duty grease gun with a pressure gage on it.
Any suppliers for such things these days? I could do the same thing
with a porta power hand pump but using oil is such a mess to clean out
of the pipes.

We use the stainless steel pump with distilled water for our testing

I test some stuff in a small tank. I fill the tank with water, and
then attach a hydraulic hose from the pump on my press. Very little
oil gets in the tank. I would think you could do the same except add a
longer water-filled line, which should keep your parts clean.

What's that Lassie? You say that RoyJ fell down the old
rec.crafts.metalworking mine and will die if we don't mount a rescue

McMasterCarr has these. About $200-$300 IIRC.

I swear I saw one for less than that. Keep looking around. When I
was thinking of getting one I was looking through a lot of catalogs.
Sorry I can't remember which one.

I ended up modifying a grease gun. a cheap harbor freight air powered
one. It would go up to 1200psi in my application, but I think a
better quality one could go higher.
