Whats up. I was pressure testing some stuff and noticed a new jic hose leaking (underwater) from in between the fitting and the part of the hose that threads into the fitting. Swapped hose and it stopped so its the hose.
Has anybody experienced this and is there a way to fix it?
Seems you figured it out all by yourself.

I have wondered to myself why jic is the standard. It’s crap. There are lots of choices. Look at hydraulic flat face o-ring seal connections commonly used for hydraulic fluid. The seals are dirt cheap. The connections don’t rely on being super tight. And they are stronger. Is it laziness on the part of the industry or did I miss something? Pipe thread and jic adapters suck. We could do better.

are all of your jic pieces stainless? or do you have brass fittings?
check that your male bevelled edge isnt ruined from over tightening
So how do you think your seals will hold up to the cold Solvents?

Check chemical material compatibility. FFORS. (Flat face o-ring seals) are common in all materials and used in both hydraulic and automotive air conditioning systems. Check with a hydraulic shop. Viton or buna n for butane.
I’ve also had workers who assumed “hand tight” was appropriate on JIC.
“I’ve never had any leaks…”
More like you’ve never had a hydrocarbon detector.
JIC works, double ferrule instrumentation (compression) fittings are better.
