Silverback Automotive Tire Gauges are designed with accuracy, durability and quality for the automotive professional in mind. The Silverback gauges are produced by a third generation, family owned business specializing in air gauges and inflator gauges. Once you have the opportunity to hold one of these air gauges in your hand you will immediately know you are holding a tool for the professional. These well balanced mechanical gauges are made of the highest quality nickel and brass materials with a premium chrome finish. But it's what's inside the gauges and the care in the production process that makes them special. Highly polished barrels, precision internal springs, proprietary lubrication and other high quality components, all work together to produce a gauge that is extremely accurate throughout a wide span of PSI. Every gauge is tested at three different PSI points for accuracy before leaving the factory.
