Can't believe I didn't buy it sooner

I have a full set of OTC adapters that fit perfectly. I bought it because the car had a very small leak that nobody could find. With this tool, the pressure in the oven was shown exactly when it was. My hand pump stays in the case now. I am an ASE L1 Master with 34 years of experience. Nothing impresses me more. This tool made an impression.

Can be replaced with Snap-On hand pump

I have a Snap-on hand held coolant pressure tester. Long-sought Pneuma. Snapon wants around 300. 😒 Searched the internet and found this. Dice and ordered it hoping I could make it work. And it worked! I swapped out the hose with a fitting at the end for a snap-on. I connected an air hose to it. Tested under pressure on the machine, everything works! Thanks to Astro for this and thanks to Revain for providing this product.

Well, none of my adapters will fit this quick connector, but I removed the tubing from my hand pump and plugged it straight into this block. Forget it, never go back to a handheld device. It takes about a second to build pressure, which is great! It does an excellent job of draining water from the

Great alternative to overpriced testers!

I bought this as an alternative to the Snap On version which gross $281 and I'm glad I did, it's the same tool. Part of our preventive workplace inspection involves pressurizing the cooling system on Class 8 trucks and using a hand pump to pressurize these large systems is time consuming and tiring. This allows them to be pressed down in seconds and you can adjust the pressure you want to press them with. The pressure release button at the end of the hose is a handy feature as it allows you to…

  • Nice to use
