Review on Yosoo 4X Tyre Valve Extension for Trucks & Buses, Dual Flexible 140mm Adapter with 2pcs Clamps by John Huskisson

I have tried so many carbide valve extenders to fill and calibrate my double RV. Nothing worked the way I wanted it to. Most had a ball valve that was difficult to fill or read. These puppies solved that problem. Solid brass construction and good STANDARD Shrader valve. Flexible so I can get to the internal duals without using the elbow braces. I highly recommend these valve extenders if you have problems like mine.
