This bracket lets you use a tire inflation hose or a valve extender on your 16" wheel with a rubber valve stem. It supports the valve stem to keep it from bending and twisting as your wheel rotates.I had hoped that these would solve my problem in supporting the rubber valve stem on my Winnebago motor home with 16" wheels. Not even close.
First they do not fit - See pic. Nothing like the picture on the product page. Perhaps my stems are "too" long (2-1/8") but they are what I have.
Second - the rubber grommet is about 1/4" thick and the threads on the stem are 3/8" long so, if I managed to get them on the stem there would only be about 1/8" of threads left for the valve extension - whose female threaded end is about 3/8" deep. See pic.
The last picture shows the valve extension screwed onto the stem. As can be seen - its threads are so deep there is no way it could get tight enough to contact the valve core in the stem with that grommet in place.
These must require very special rubber valve stems that are very short and have very long threaded ends.
Very disappointing.
tore the valve stem off my dolly wheel and destroyed the tire. the design needs to provide better clamping to wheel.
