The brass sleeve I have put on the outside of the tank by mastake and it worked fine.

The brass threaded sleeve gets aeropoxied from the inside of BVM kevlar tanks. the tank stopper threads into the brass sleeve and allows easy replacement of your pickup line.

Looks nice and more durable. I see the brass ring but not sure how you secure the fitting to the tank?
