How do I get the cap back on before all the air comes out?
This may sound like a silly question, but it comes up every year or so.
The valve should retain air without the cap in place. If it does not, push the colored button on top of the stem down and rotate it 1/4 turn. It will then pop up, and the valve will seal itself. The valves are a popet type valve that rely on spring pressure and air pressure behind the valve to opperate.
When inflating, the air pressure in the pump overcomes the pressure behind the vlave popet, and the spring tension on the popet. If using a shop vacuum to to the main inflation, it is a good idea to open the valve before inflating. Then a quick push in and a 1/4 tune with a finger will set the valve back in place.
Can you tell me what the black fitting is for that came with the warranty envelope? The plastic fitting goes into the valve and with a twist it will lock into place. It requires a 5/8-inch id hose to make a tight fitting. If you purchased a wonder pump (double action pump) the fitting needs to be adapted to work. Simply wrap some black tape around it to make the ribbed fitting larger. Then the fitting will fit into the hose of the double action pump tightly.
The Valves are a poppet type valve. Push down on the colored button in the middle and turn 1/4 turn to deflate or to seal the valve after it has been in the deflation position. The valve does not have to be in the deflation position when pumping the tubes up. Air pressure moves the poppet off of its seat, and the air goes in. Then when the adapter is removed, there is no air loss.
