What Makes Stan's Sealant Injector a Shop Must-Have?

The Stan's Tubeless Sealant Injector makes adding or topping up sealant a clean, no-mess process every time. The 150ml injector syringe is sized for modern tire volumes and the higher sealant quantities that wider tires require, so you get a proper fill in one shot without wrestling with small-volume tools or spilling sealant across your floor. It's a simple upgrade that makes tubeless maintenance noticeably faster and less messy.

Compatible with both Presta and Schrader valves, it works across road, gravel, and mountain bike setups without any adapters. The large-volume design eliminates the drips and waste common with smaller injectors, and since sealant goes straight in through the valve core, you don't have to deflate the tire to add it. A straightforward tool that anyone doing regular tubeless work will reach for constantly.
