GKEEMARS Pneumatic Foot Pedal Valve FV-320 1/4” NPT Threaded Rubber Nonslip Pressure Control Foot Operated Pedal 2 Position 3 Way

No leaks. Feed about 100PSI of air through it to power an air-over-hydraulic ram on my press.

Works great on an pneumatic jack for my shop press

Bought this to attach to my hydraulic press after upgrading it with an air jack. Works great. Holes could be a little spaced out better for making connections but you still can do it

Really good fitting worked like never been broken on my tire Patch stretcher....

it is a good foot pedal

I use this to control an air over hydraulic ram on my 20 ton press, it works great and lets me keep my hands free to fixture the items I'm pressing on the press blocks

The actual working parts of this pedal are just a small, rectangular valve block with threaded ports. When you step on the pedal, it pushes open a spring-loaded valve in the valve block. A very simple device and it works. My pedal came with a hard rubber pad on the bottom. Better than nothing but it does slide around on my concrete floor.Be aware that the input/output ports are very close together. There's a reason why they package this with push-to-connect air tube fittings. If you're thinking (like I was) of threading in two, standard 1/4" male air fittings and using normal spring loaded couplers, it won't work. The fittings will thread in but you will not be able to fit two spring loaded air couplers right next to each other b/c of how close the input/output ports are on the pedal.This was a bummer for me. What I wound up doing was permanently threading in a 3-foot leader hose extension directly into the pedal output, no fittings. That left enough room next to it to fit a standard spring loaded coupler on the input, so I could disconnect the pedal from the compressor when not in use.I have quick disconnects and wheels on everything in my garage shop b/c it is a garage shop. I'm short on room, overpacked with tools and need to be able to move stuff around and/or store it when not in use.If I had to briefly sum up this pedal:- It works. For how long is anyone's guess. It's cheap stuff.- The design of the pedal is horrible. The Input/Output ports are too close together to use standard air fittings.- For occasional use, like I'll be using it with my HorribleFright press brake with air over hydraulic conversion, it will probably last many years.- Would not use this for heavy duty use or if you make your living with your tools

A little small, but will made.
