In your place I would invest in a coil of new copper pipe, some new Swageloks and some PTFE tape and re-do the connection at the helium outlet - using only one reducing bushing not two and making sure that the reducer does not bottom out in the fitting without properly compressing the tape (I am assuming that the outlet has a tapered thread, although from the picture it might be one with an O-ring seal). Then take one, unbroken length of pipe to the connection in the GC, and re-do that with a new nut and new ferrules. Follow the Swagelok instructions to the letter.
