Slime Self Healing Tube

The tube comes pre-filled with a liquid sealant. When a puncture occurs, the air pressure inside the tube forces the sealant into the hole, where it quickly solidifies to create a flexible plug.

It is designed to seal small punctures caused by thorns, glass, or wire, typically up to 1/8 inch. It will not repair large gashes, sidewall tears, or pinch flats caused by low tire pressure.

Yes, because of the added sealant, these tubes are noticeably heavier than standard, non-sealant tubes. If you are a performance-focused cyclist looking to save every gram, you might find the extra weight undesirable.

You can use it with any tire, provided the tube size matches your wheel diameter and tire width. Always check the sidewall of your current tire to ensure you purchase the correct size.

Installation is identical to a standard inner tube. Just be careful not to pinch the tube during installation, as the sealant can be messy if the tube is punctured before it is fully seated.
