Is this the right inner tube for my bike?
This 20 x 1.5-2.125" Schrader inner tube is designed for 20" folding bikes and children's bikes. Check your existing tyre size and valve type before fitting.
How does a Slime self-sealing inner tube work?
The tube is pre-filled with Slime sealant. As the wheel rotates, the sealant coats the inside of the tube. If a compatible tread-area puncture occurs, escaping air pushes the sealant towards the hole, helping to create a plug and seal the puncture.
FAQs
What size puncture can Slime seal?
Slime can seal compatible tread-area punctures up to 1/8" (3mm). It cannot seal punctures outside the tread area, including some sidewall punctures and pinch flats.
What is a Schrader valve?
A Schrader valve is the shorter, wider valve commonly found on many bicycles. This tube has a Schrader valve, so make sure your bike uses the same valve type.
What if the tube does not seal a puncture?
Check the tyre for the cause of the puncture, remove any object, reinflate the tyre and rotate the wheel to help the sealant reach the puncture. Larger gashes, sidewall punctures, pinch flats and some other types of air loss may not seal.
How long does the Slime sealant last?
Slime recommends replacing the tube after 2 years for maximum puncture protection. If the tube is still in good condition, more Slime Tube Sealant can be added.
Can the valve become clogged with Slime?
If this happens, Slime recommends cleaning around the valve, removing the valve core and cleaning the valve and O-rings with a wet cotton swab before reinflating.
