Machined Thumb Knob For Bottle Jacks (Round) Open/Close Valves

We save you the hassle of using the 18" long handle to open and close the pressure release valve on any of your bottle jacks or long rams. It is fully machined out of steel with a black oxide finish and built to last. The inside diameter of the thumb knob that fits over the pressure release valve is 0.37"

To install you simply press out the roll pin on the ram, slide over the SWAG machined thumb knob then reinstall the roll pin.

Note: If your bottle jack release valve has a flared or "smashed" end, or a cast cross pin, you will need our 3-D printed thumb knob which can be found HERE.

Useful enhancement to your hydraulic cylinder pressure release valve

I installed one of these on the cylinder on my shop crane and my 20-ton press. The knob fits right on the shaft of the valve on the press's cylinder, but I had to drill the other out to 7/16" to fit my shop crane relief valve (not a big deal to me). These are handy and I feel it gives me more control than using the jack handle. Plus, I can have one hand on the SWAG knob while using the jack handle to lift for really precise control. I'd buy these again if needed.

Loose Fit

I am pleased with the quality it's good value, but it fit a bit loose, so I drilled and tapped it for a 10-32 setscrew now it's perfect. Thank you for providing quality products to all of us DIY guys.

Knob for harbor freight press

It got here quick, even during Christmas time. It works perfectly! Swag offroad is the real deal.

Awesome

Awesome little gadget makes it nice. Only issue I had with it was that it was machined too long for my bottle jack. Or the cross pin hole was drilled too deep. I had to grind the body shorter so that the needle would seat before the knob hit the body of the jack.
