it's the lttle barrel at the end, it's way past bending back I'm afraid, tried that first.

drill the rims and upgrade to a decent reliable valve

What do you mean you bent the screw down seal? If you're talking about the little screw ring that goes over the valve and sits on the rim, it's not really needed. You can do without if you want.

Or if you're talking about the little barrel at the end, just bend it back and be careful in the future.

I managed to bend the screw down seal on my son's 20" wheeled bike inner tube.
First thoughts were to get a new tube, but that's proving somewhat difficult.
Is it possible to strip down the valve and fit a new bit, like you can with schreader?
