Imperial 4 Port Gauge Problems Model 644-CCJ
Does anyone have a set of imperial 4 port gauges model 644-ccj that has had problems with them?? I have a set that will not hold a good vacuum below 400 microns, I can pull down a split system to 160 microns, but as soon as I shut off the pump, vacuum jumps to 440 microns, tried pulling just on a recovery cylinder, same problem. Sometimes after I valve off the vacuum port then re open the vacuum port it will not pull a vacuum through the manifold. I am ordering a rebuild kit for the valves hopeing that will solve the problem. Any other ideas?? How about different manifold suggestions?? Looking at a Ritchie Titan 4 port set.

And do that, either SLC's setup or Mike19's on page 3. Problem solved.
