So I have this Atlas cylinder I'd like to use in an upcoming build. I'm sure it has class 1 seals which means it will work fine with air or hydraulic fluids. I took the caps off and it operates easily with just my airgun in the ports. The etch on the side says it's an H025-PB2-0100-4NCSV 14.000. From what I'm able to gather it's a 2.5" bore, 1 inch rod with a 14" throw, however I'm unable to find the correct port bushing for it. There was a 0.75 bolt plugginh onr port, however I know it's not a 10 thread. I tried a 1/2" to 3/8" bushing at TSC today and it wouldn't thread in. Just wondering if anyone might have an idea what size I should be looking for. Unfortunately the Parker/Atlas site is not loading for me and what information I was able to pull off of a pdf was just a little jumbled around since it was for every possible configuration of this heavy duty cylinder series. I'll attach a pic. Thanks!

I think you will be looking for an 'ORB' fitting for that now whether it's metric or standard is the only question.

http://www.goodvibesracing.com/orb_fittings.htm this is what they look like. Just the first goole link I pulled up.

hope it helps

Found them at a local hydraulic store, thank you. now I just need to figure out how to up my rate of travel. This ram is about 2/3 the speed of my 2x8 cylinder. I'm using 3/8 tubing so maybe I should up it to something with more flow?

The key to controlling the speed of an air cylinder, ... is in controlling the EXHAUST.

There are a variety of "quick exhaust" fittings that will help you with that.
