Stan’s NoTubes Rolled Gold Tubeless Sealant

A biodegradable, water-based tubeless tire sealant built on a natural latex formula, designed to seal punctures at a lower dosage than many competing sealants. It’s sold across three bottle sizes for topping up a single tire or filling several.

Stan’s rates the sealant for use across a 35100 PSI range and states it can seal holes up to 7.8mm at 100 PSI; roughly 35 mL is the recommended fill for a 700x28c tire, and one 500 mL bottle is stated to treat up to 16 tires.
