The world of cycling is constantly evolving. In the early 2000s, the first version of Stan's Injector was released to provide tubeless users with a tool that meets the demands of larger tire sizes and the associated higher volume of tire sealant. To ensure a puncture-free riding experience, the Tubeless Sealant Injector is prepared for all formats. With an extra-large filling volume of 180 ml, you can fill large-volume tires, whether MTB, gravel bike, or road bike, with the appropriate amount. A detailed scale and the filling volume recommendation on the packaging help you pour in the right amount. The 360-degree rotating valve adapter can be easily and quickly attached to the valve and is universally compatible with Presta and Schrader valves. A valve key is included for opening Presta valves. A cross-slotted valve in the fitting and the unique vent channel in the syringe body ensure precise filling of the sealant from the top. A Stan's plug is included for hanging on the workbench or for leak-proof storage in the toolbox. To ensure nothing goes wrong during filling, a step-by-step guide is printed on the syringe body.
