Review on JACO Lightning Tire Chuck F NPT Tires & Wheels : Accessories & Parts by George Mendoza

I recently had to replace my digital tire gauge/inflator and was very disappointed with the European style air chuck. The previous one worked well enough, but this new one didn't work at all. I had to hold it on the tire stem to get a good seal. These new Jaco Lighting cartridges looked too good to be true, but I took a chance. They are lined up right on my sensor and they are amazing. You simply slide them onto the rod's stem and snap into place for a very secure, airtight connection. When you're done, just press the release button and they'll pop out with minimal air loss. I've only had them for a short time now so it's definitely too early to tell how well they will work over time, but so far they're amazing.
