3-D Printed Thumb Knob For Bottle Jacks With A "Flared" or "Cast Cross Pin" Open/Close Valve

We save you the hassle of using the 18" long handle to open and close the pressure release valve on many of your bottle jacks or long rams. This 3-D printed knob is designed for the flared or "smashed" pressure release valves as well as the "cast cross pin" release valves that are found on many newer bottle jacks. These alternative styles of release valves are less expensive to manufacture than the machined round valve with the pressed in roll pin.

The flared end or cast cross pins on these bottle jacks vary significantly from part to part, hence a machined knob does not make a good candidate as it will not conform to the different profiles on the bottle jacks.

To install the 3-D printed knob, you simply press the knob over the release valve and tap it down into position with a rubber mallet....that's it.

NOTE: If your bottle jack has a round stud with a cross pin, you will need our machined thumb knob which can be found HERE.

Great Little Knob

If you spend any time with your press, you know dealing with the handle to release the pressure can be a time suck enter this little beauty. Works perfect on my Harbor Freight 20T air actuated bottle jack.

3 D Printed Bottle Jack Knob

What a handy device. Put one on one of my presses, So much better than fiddling with the pipe handle. Going to get more for my other presses. Thank you.

Item arrived and worked as described. Makes working the bottle neck press much easier than moving the bar back and forth.

Printed Thumb knob

Worked well. I had to grind a bit off the cross pin from the H/F 12 ton air over hydraulic jack I've installed but once it was on there have been no worries.
