This is it. MUST buy
This is the tool you need to replace both the low and high side valve cores (schrader) of your car AC system. The hole is actually deep enough to fit the spring of the larger high side valve core. The other tools do not fit, I have tried 2 other Chinesium trash tools. It's also durable and doesn't melt like the other garbage under torque. Had to use pliers to twist them but it's sturdy and high quality. Worth the extra dollars.

Works great
Great price. Works perfect. I had to put pliers on it to loosen the old valve and it did not crack. Impressive.
