Slime Tube

The tube comes pre-filled with a liquid sealant that remains fluid inside the tube. When a puncture occurs, the escaping air forces the sealant into the hole, where it instantly clots to create a flexible, long-lasting plug.

This tube is designed for 27.5-inch wheels with a width range between 1.75 and 2.125 inches. Always check the sidewall of your current tire to ensure your specific tire size falls within this range before purchasing.

No, this specific tube is equipped with a Schrader valve, which is the wider, car-style valve. If your bike rims are drilled for Presta valves, this tube will not fit without modification, which is generally not recommended.

The sealant is designed to handle punctures up to 1/8 inch. If you experience a larger cut, tear, or sidewall damage, the sealant will likely be unable to seal the hole, and you will need to replace the tube.

The sealant is formulated to remain effective for up to one year. After that period, the sealant may lose its ability to actively seal new punctures, though the tube itself will continue to function as a standard inner tube.
