All of the extensions came from the parts department at Foley RV Center, A/K/A Airstream of Mississippi. Brand name is Wheel Masters®. The straight extensions are aluminum, and longer than the plastic ones that came with the Interstate.
The J-shaped extensions are aluminum as well, coupled with additional straight extensions to lengthen the long side of the J. Now all of my valve stems are reachable with a standard chuck air hose; no need for a double-chuck. That means that, on the road, I can air up at any service station, and don't have to look around for a truck stop.
