OTC 2510A Stinger 10,000 PSI Foot Operated Air/Hydraulic Pump for Rams, Presses, & Hydraulic Pullers, CHROME

You get what you pay for. Yes it is more expensive to buy this brand name but it will last way longer. I have been using this brand pump for over thirty years and it never gave me any problem.

Arrived and worked as decribed

Air over hydraulic. Works quick and it’s quality OTC. You can use it on a lot of different rams. Good price. Slow on shipping. I would recommend this company

This works great on my 12 k 4 post lift .. Its a little slower then original but lifts heavy trucks.

Pump installed and worked so well I bought 3 more for my roller jacks

This was really simple and easy to operate. It worked flawlessly and better than any air over hydraulic pump I have tried to use.

This hydraulic pump works very good. It frees up both hands so you can hold the parts in place that your working on. The hand pump on my press took forever and a day to operate it and I could only hold the parts with one hand and operate the hand pump with the other. The OTC pump saved a lot of time.

This is very good for the price. The key to getting the full power from this type of pump is in the larger capacity hydraulic tank like this has. The cheaper models have only 1/2 the volume reservoir and will not create the same power in the last 1/2 of ram movement of your device. I know, my last one was the smaller size and that's what happened to me. My local hydraulic shop explained this to me, and were 100% correct after using this hydraulic tank size. It's like a different tool with this pump sized tank.
