Review on 2 Truck RV Car Bike Motorcycle SUV Vehicle Dual Wheel Tire Valve Extender Extension Adaptor (9 by Wayne Gilbert

I wanted to add TPM blocks to my dual drive van so I had to lengthen the valve stems to keep the pressure blocks from getting pinched by the wheel covers. I ordered these extensions to complete the task. One of them separated 10 miles from my house, another blew off leaving a flat tire and dropping the TPM transmitter module somewhere along the freeway. The whole structure is broken, mixed metal pipes are lying around, valves don't work well. Don't buy if you don't enjoy getting stuck on the freeway or buying tires along the way.
