Stock Brake question



Where would one find the packing or whole nut (with rubber packing inside nut) that slips onto the bladder inlet/outlet tube? Mine doesn't tighten around the tube as I screw/tighten the nut to the bleeder valve assembly, it just scews down onto the bleeder valve assembly but pulls off the bladder inlet/outlet tube easily by hand plus leaks when I try to bleed the system. A part number or a place to purchase the nut would be gladly appreciated!

One other question, on the expander tube(bladder) itself the inlet/outlet tube, if you were to loosen the nuts that hold the tub in place, would that allow the tube to move freely in the expander tube, but if it were to remain loose would it leak around the base of the tube and bladder?
