Coworker lost the fitting for an outlet on a liquid chromotagraphy instrument and I called the service tech who special ordered a tiny plastic piece and installed it. The next morning there was a puddle and the tech said it might need to be tightened further. That didn't work. The first pic is how it should connect on the inside cover of the outlet port. With the water running it seems to work (water comes out the front of the cover). But when the beige tubing is attached on the outside of the cover the outlet port leaks on the inside of the cover. I tried some new beige tubing to make sure a clog was causing the leak but it still leaked. Any help would be much appreciated.
In the second pic the bottom hole is the outlet port where the connection leaks on the inside.
In the third pic the beige tubing leads to a drain and everything appears ok until you pop the cover off and discover water pooling inside the instrument

Unfortunately, we would need to know more about the instrument and the connections before we could even guess at an answer. Those are not typical plumbing connections, so you have to depend on the manufacturer or his representative to supply the proper item(s).

the beveled ferrule is on backwards
taper should be into fitting, not nut

my friend friom SC.. i don't see a bevel inside the female fitting. i also don't see a flat surface either for the ferrule to bump against if in fact the flat end in first is the correct orientation.
if it is compatable and won't do any harm, i would put a dab of silicone grease and try again..

It appears that the white tapered cone should have something(perhaps a rubber grommet or washer) on the short piece of tubing before the flat of the tapered cone that should seal against a flat surface inside the machine. The hollow nut should apply pressure to the cone and squish the washer into a watertight seal. I suspect that it fell off when being disassembled and somebody didn't notice it. If you screw it back together about half way, I am guessing that the tubing will still move about a sixteenth of an inch in and out of the machine. If it does, you are missing a washer of some sort. If the tube with the tapered cone had a metal screw, then I might believe that it was meant to cut its own groove into the plastic to seal, but with the coarse threaded plastic, it isn't designed to do that; it needs to compress a soft gasket material.

Wrong piece was installed by service tech. Coworker ordered the correct piece supposedly. I will take a picture when it comes in
