The kit includes several vented plugs so it even works with double-tube systems and is guaranteed not to pressurise your pitot static system. The blazing yellow colour of the included foot-long, ANSI-compliant and weather-resistant reflective remove-before-flight streamer stands out equally well in daylight or darkness under all weather conditions, so it can't be missed. The kit comes complete with three different-sized pitot tube plugs, our unique streamer, and two rust-resistant coated triangle rings. The kit can also be used to prevent insects from plugging your fuel vent, which is known to cause loss of power with Cessna, light sport and home-built aircraft. WARNING: CHECK WITH YOUR AME AND CONSULT YOUR OWNER'S MANUAL BEFORE USING A FUEL VENT PLUG.
