Review on 🔧 Pacific Dualies 18180 180 Degree Valve Stem Extension - Enhance Tire Maintenance with this Set of 2 by James Baker

These valve stems, while geometrically correct and structurally adequate, only have a knurled nut for attachment to existing valve stems. It is very difficult for my twin wheel truck to attach these extensions tightly enough for comfort. When I first bought it I thought the nuts were flat so you could tighten them with an open end wrench enough to be reliable. Keep in mind that if these extensions come loose at all, the tire will slowly deflate.
