Well this doesn't solve your problem but LPS2 is much better.
I tape the straw to the nozzle. I mean masking tape (believe it or not it is the best thing) around the whole nozzle and then on to the straw, and th en use a zip tie around the straw which is tightened by pliers. Well you ta ke the cutter and nodlnees pliers and place them so you get maximum leverag e. Make it "tick" one more time.
It is the nature of the material, not only are some parts possibly nylon, f or which glue is prohibitively expensive, but the oil itself. I have consid ered high frequency welding but I do not know anyone who does that.
With WD-40 and even moreso with LPS2 if you put it in a non-pressurized ves sel is will lose its aromatic components and thus some of its efficacy. Sti ll beats most stuff.
