I glued it on, It still works but it bursted under pressure because of the bad quality, I was asking what section neoprene is in. I looked before but I couldn't find it.

For the pilot valve, you dont need that quarter inch pipe nipple and the coupling, you can take both of them off the and just keep the quarter inch ball valve.

Look in hardware and you can find neoprene washers, just take a small screw and a small washer and bolt it on, and it will stay on.

The neoprene washers will be in the "specialty screw drawers" section...oh at Lowe's, I don't remember any at Home Depot.

The problem was the hot glue, hot glue doesn't bond, you should have super glued :) yea washers should be in where starman said, they are usually in drawers.

I am don't understand how the hot glue caused the neoprene to break.

Thanks! :)

it didn,t break it just got messed up by the pressure, since it wasn't properly bonded to the piston.

But I heard a little popping noise. So You Think If I went out and bought super glue it would still be cool.

It leaked only after it popped, I will try it tommorow, if it breaks again I will just use rubber. Since I already casted the piston.
