BTW the valve you pictured ...I forget the name...but their claim to fame is that they are capable of blowing up by mouth.

For the tethers just go to a $1 store and pick up some nylon dog collars..the ones with the plastic buckle snaps...they work great and the price is right....

;)Norm....key word was "special"...[which incidentally I have]...just trying to point out something simple:cool:
and that's what they make electrician's tape for...note it on the green hose:D;)
...

Just for the record...you don't need a special adapter for the Halkey Roberts...a piece of garden hose works just fine.

Years ago I had a tube with the tire type valves...bought an adapter so I could use the type of pump you pictured...so if you have the tire type valve you should be able to find an adapter.
