Valve Core Gripper Remover/Installer Tool XLT (larger bore than regular gripper tool) which removes stubborn/broken large/big bore valve cores most of the time by gripping the rounded tip of the valve core depressor usually even if the valve core itself is broken. Simply  push down on the top of the valve core gripper and place the gripper on the tip of the valve core depressor, hold the knurled handle down, twist the valve core and pull up on the included key ring, which then safely, easily removes the stubborn/broken valve cores in most cases. Can also be used to install large bore valve cores. Designed for use on large bore valve cores including HVAC, automotive AC valve cores, truck tires, aviation, fire extinguisher equipment, hydraulic systems and more. Durable stainless steel construction. Made by EB Tools Inc. Click on link below for more info and videos. Measures approx. 4 1/4" L, stem remover measures approx. 1 1/2" L.

XLT Gripper- The PCRT-3 is our extra large bore tire valve core tool. It is constructed out of durable 303 stainless steel. It won''t rust and it won''t bust. The XLT Valve Core Gripper is a safer and easier way to install and remove big bore valve cores. Stuck valve cores are no match for the XLT Valve Core Gripper. If you can twist the core, you can remove the core easily. It eliminates the accidental dropping and subsequent loss of valve cores thanks to the patented gripping action at the tip of the tool. It works in four easy steps Push it, Clip it, Release it, Twist it. It is designed for use on Semi-truck and heavy equipment tires that use the Large Bore Valve Core. It''s extended length allows you to fill your tire with air before installing the core.|XLT Valve Core Gripper Removal Tool- Extended Length and Size for the Commercial and Heavy Equipment Tire Professional.

My idea of inventing a valve core tool that grips the valve core began several years ago when supermarkets began retrofitting their systems to run on the new HFC refrigerants. One of the requirements was to replace every valve core during the refrigerant change out. A good number of the valve cores were stuck or broke apart during removal and so many of those valve cores never got replaced.  

A couple of years passed by and I foundhttp://www.valvecoretool.com/index.php/about/81-general/72-about-valve-core-gripper-tool myself in a spot wrestling with a stuck valve core that just would not come out.  Removing the valve core was a must since it was in a water based system. I tried using the usual tools like needle nose pliers without success. So I screwed the valve core back into the valve and the vision of creating a valve core gripper device was revisited once again.

I put pencil to paper and created a few designs. I had a crude prototype put together and I returned to remove the stuck valve core that defeated me two weeks earlier. I clamped the tool onto the valve core and began pulling and unscrewing at the same time. To my amazement, the valve core popped out with little fight and all in one piece. That was certainly not what I was expecting to happen. Stuck valve cores never come out in one piece.

I began testing the valve core gripper out on areas of refrigeration systems that I know are prone to having stuck valve cores, like steel drier cores, and each time the valve core has popped out in one piece without much of a fight.

That was not what I was expecting to happen. Stuck valve core never come out in one piece. During testing there were a few things I did not like about the valve core gripper so I optimized the design to what you see today.

I hope you enjoy using your new valve core gripper as much as I do!
