Review on 🚚 Pacific Dualies 18101 MAX EZ Air 7" Braided Stainless Steel Valve Stem Extensions with Small EZ Wire Clip - Ideal for Ford E350/E450 Dually Trucks, RVs, and Motorhomes featuring 2" Round Vent Holes by Noah Trigg

For reasons of age, I am replacing all 6 tires on my 2006 C camper van with new Michelin tires. The RV has only driven 30,000 miles and has never seen winter. I have also decided to replace all of my valve expanders due to their age. I bought these Pacific Dualies 7 inch extensions for my two inner wheels on a dual setup rear axle. Both new 7 inch expanders are installed well BUT you can't check tire pressure. Luckily I tested them before I mounted the wheels and tires. I reinstalled my old expanders (which look identical to new ones) and they work as expected and I can check the tire pressure. Very disappointed with the product. Since both extensions didn't work, there must have been a design or manufacturing issue.
