now that we know you want to length your hose. Go to a good bycicle store and get a schrader valve adaptor. Then you can add a line
VJ: I wish it were that simple. I've spent hours -- actually, must total days by now -- on the 'Net looking at bicycle parts, Schrader companies, hydraulic companies, etc., etc., for the sort of thing I want... with no success. And I've emailed a few of these companies, describing exactly what I'm looking for, with no luck. What I was looking for would be some sort of cube-like connector, which would make that sharp right turn while not sticking out much past the stock valve; people make this sort of thing on a larger scale, for hydraulics and such like. I even researched the thread diameter and pitch of Schrader valves, thinking to have one made up by some machinist.
What I want to do is make a sharp right turn at the user end of the hose, add a hose (10" - 12" or so), and come out the front of the side cover. What has been stopping me is that there is less than half an inch of clearance, underneath, between the end of the stock Schrader valve and the side cover. I've tried adding right-angle valves and more acute-angle valves, but the cover won't fit back on if you do that.
If you have some specific
part in mind at a bicycle store, I'm all ears. Otherwise, sorry, I don't really follow the drift of your suggestion.
