Amprobe ULD405

This is an excellent yet pricey tool for detecting air leaks. I had rebuilt my brake protection valve plumbing and tested for leaks with my trusty kids bubble mix as I have always done. No bubbles on three checks at different times. On another members suggestion in the Newell group, I decided to spring for this. It heard a leak that the bubble solution did not find. Once I redid the nipples and tightened things back together, the tool doesn't detect any air loss. Of course I do have other air leaks that I need to sort out. Just another tool for the bus...

I have a 100 buck Reed that works ,I like

To be honest, I was a holdout on buying this. Called old fashioned, but spray bubbles are my go-to tester. That and two fingers for power testing on 120v. Newells are a pain in the a$$ with all the push fittings used that degrade over time. it's a never ending chase. That said, any tool that works for someone is better than none.

Push fitting always leak,my Country Coach every fitting was a push end even the cheapo ultrasonic leak detectors will pickup a pin dropping on cotton, glass companies can find where a windshield is leaking with one

I think my windshield leaks a bit of water inside. How would I use this tool to pin point the leak? Drive it and aim the tester?

My tester has unit you set on the dash that sends a signal of some type the tool pickups, I saw it being used at a glass shop and had to have one you know how that goes  ,you don't use the unit when looking for pressure leaks ,your theory will probably work with your tester

I think I can take the lazy way out and just put a tiny bead of Lexol around the whole thing and call it good!
