Overview
Can You Use Muc-Off Sealant in a Standard Inner Tube?
The Muc-Off Inner Tube Sealant is formulated specifically for use inside inner tubes, including TPU tubes, and seals holes up to 4mm without a tubeless conversion. The water-based, non-hazardous formula uses cutting-edge molecules to seal holes quickly, works on multiple punctures, and contains corrosion inhibitors.
The bottle has its own filling tube, and the 300ml size comes with a valve core removal tool and an O-ring for Presta valves. It works with Schrader valves and with Presta valves that have a removable core, and no tubeless rims are required. The 300ml bottle has a dosage scale on the side, and Muc-Off says the sealant does not dry out and lasts the life of the inner tube.
