Setting up tires tubeless has never been easier—Rene Herse Supple Sealant includes ground walnut shells and is specifically formulated to seal supple tires, both during installation and on the road, if the tire suffers from a puncture or small cut. Our new formula uses only fine particles, so it’s easy to inject through the valve stem, yet it seals punctures effectively.

Supple Sealant is made from natural ingredients (see Tech Specs) and cleans up easily. Supple Sealant is fully biodegradable and does not pose any risk to the environment in case of a spill on road or trail.

500 ml (17 oz) bottle is enough for 4-6 tubeless installations. Also available in an economical 1000 ml (34 oz) bottle.

Made in Japan.

Pro Tip: Supple Sealant works great with all tires, not just Rene Herse tires. The ground walnut shells interlock to plug cuts in the tire more effectively than sealants without solids.
