USAG Tire Deflator Silencer (425S) - identical to Facom DR.SIL. Developed for Facom by the French equivalent of OSHA (INRS) - significantly reduces shop noise levels when tires are deflated by removing the valve core. Noise levels maintained below 85db without impacting the deflation speed. See video
