Stan's No Tubes Tire Sealant Injector Makes Tubeless Setups Easy Once you get your tubeless rim tape and valve installed and you have a tubeless tire, you'll want to add tubeless sealant. One of the easiest ways to add sealant is with a sealant injector. The Stan's No Tubes Tire Sealant Injector has a larger volume that gives you the ability to inject sealant into today's higher-volume mountain, gravel, and road tires with a single fill. The new press-on adapter presses directly onto Presta and Schrader valve stems for quick fills without threading or additional parts. A cross-slit valve in the fitting paired with a unique air-relief channel in the injector body allows a precise fill of well-shaken sealant from the top for a convenient set-up with zero mess. With the included hang plug, you'll be able to store your sealant injector in your toolbox without the mess.
