Schrader Valve Extension Problem

Our 2004 E450 rear duals have a braided flexible valve extenders.

The problem is one of the braids has been cut by a sharp edge in the wheel cover and we are basically on the road.

So, while I want to replace these extensions with Tire Man or Borg rigid type it is not in the cards until we get on home turf.

So my question is, are these braided flexible extenders pressured up all the time OR only when the outer valve is pushed in?

If they are pressured up all the time then my only remedy on the raod is going to be to remove them. The tire is NOT LEAKING as it presently sits BUT I do not know how much damage there is beyound the frayed braid outer layer.

  • Depends on if or not there are two valve cores. Mostly there will be 2, so no...the braided hose will not be under pressure.......
  • Some are pressured and some are not. I'm not sure you can tell without taking one off. With a non-pressured one, you can push on the little stem that protrudes from the valve core and see similar action at the other end.
  • Move the line away from the area that is cutting it and take a closeup photo with your digital camera.

    I use my cameras all of the time to get up close when I can't.

    If the braiding is just a bit frayed, you could slip a piece of hose (that is slit open with a sharp utility knife) over the extension to protect it until you get home.

    I think the pressure is right up to the end of the extender..
