I couldn't find this anywhere else...does anyone know what pressure brake (inverted flare) fittings are rated for, especially brass ones?

I'm trying to cobble together an injector pop tester for my truck's injectors and I don't have a good way to connect the injector line to the rest of the pipe fittings I'm using. The line is 1/4" so I wondered if I could put a 1/4" tube nut on there, flare the line and use an inverted flare to pipe thread fitting.

Max pressure on the system should be 2000 psi or less, I don't know what kind of pressure brake systems can generate, that's why I ask.

 

Pressure under normal braking is around 800psi but goes to around 2000psi under heavy braking.

 

So is it safe to assume that even brass brake fittings are rated for at least 2000 psi? I've certainly never had one fail...

 

I`ve never had one fail either, plenty of rusted steel pipes though.
I would think for infrequent use you would be OK.

 

Did a quick search on "brake line pressure" -- several places talked about 'upwards of 2000 psi'.

Here's a note from some premium replacements for the rubber hose segments -- they test to 3000 psi

Sounds like it will work, but it might be worth putting some shields in place to avoid any chance of injury.

Good Luck,
