This is a great pump for a great price. This hydraulic pump was purchased for an old log splitter. It has a ¾ npt outlet with a 1” hose barb inlet. The hose barb does unthread, but I'm unsure of the thread type. I think it's Metric fine thread. I used the hose barb. The pump was installed on the splitter without issue, and the hydraulic connections were in the same place as the original pump, so the old hydraulic hoses still fit. Everything works as it should. The log splitter is back up and running.
