Review on Pacific Dualies 18090 Degree Extension by Chucky Hepler

The 90 degree valve stem is well intentioned. However, I noticed that I was having a hard time getting accurate air pressure readings and also trying to increase tire pressure. Another noted that a tire would leak in the valve stem area with a 90 degree valve stem. It is best to place the 90 degree valve stem inside the rim and use it as a jet/extension. It will probably work for most applications!
