I've got 23 ton Champion splitter. Last weekend while busting some oak, a round was stuck on the wedge and came back and ended up crushing the valve that sits on the hydraulic cylinder. The double male 5/8 "(possibly 3/4" OD) nipple broke off flush with the cylinder. The valve assembly was OK. I was able to get the broke end out of the cylinder. Here's the question, I went to a hydraulic repair shop and got a double male nipple that the shop uses on heavy equipment repairs. The salesman stated it was rated at 3000psi. But our concern was when we compared the ID. The one that broke was thicker wall and 3/8" ID and the new one was 1/2" ID. I went to another hydraulic shop and they used the same type nipple I had picked up but was informed the pressure of 3000psi was probably OK but the different ID may be for flow rather than pressure. I got home and put it all back together, everything seemed OK but I haven't split anything yet. The speed of the ram seemed OK too. Is there any concern with the nipple I installed?
