Product Information
Full details
The Schwalbe Glueless Patches (MPN: 3900.02) are essential for cyclists using Aerothan or other TPU-based inner tubes who need a reliable, on-the-road repair solution. These patches provide the key benefit of a rapid, tool-free application that eliminates the mess and drying time of traditional vulcanizing glues; however, they are specifically formulated for TPU material and will not work on standard butyl or latex rubber inner tubes.

FAQs
Can I use these on standard rubber bike tubes?
No. These patches are engineered specifically for the chemical composition of Schwalbe Aerothan and other TPU (thermoplastic polyurethane) tubes. They will not adhere properly to standard butyl rubber.
Do I need to sand the tube before applying the patch?
No, you should not sand TPU tubes. Unlike traditional rubber tubes, sanding can damage the surface of the Aerothan material. Simply ensure the surface is clean and free of debris.
How long do I need to wait before inflating the tire?
There is no waiting time. Once the patch is applied with firm, even pressure, you can re-install the tube and inflate the tire immediately.
How many patches are in one package?
Each package contains four individual self-adhesive patches.
Are these patches permanent?
Yes, these are designed to provide a permanent repair for small punctures in TPU inner tubes when applied correctly.
Troubleshooting
Patch is peeling at the edges
The surface was likely not clean or dry enough before application. Remove the failed patch, clean the area with alcohol if available, and apply a fresh patch using firm, sustained pressure.
Air is still leaking after patching
Check for a second, smaller puncture or a sharp object remaining in the tire casing. Always inspect the inside of the tire tread before re-installing the tube to prevent recurring punctures.

Setup, Compatibility & Care
To ensure a lasting seal, the area surrounding the puncture must be completely clean and dry before applying the patch. Use a microfiber cloth or your fingers to remove any road grime, grit, or sealant residue from the TPU surface. While these patches are self-adhesive, applying firm, consistent thumb pressure across the entire surface of the patch for at least 30-60 seconds will significantly improve the bond strength. Always store the patches in their original packaging to prevent the adhesive backing from collecting dust or lint while inside your saddlebag. This product is strictly designed for TPU tubes and should not be used on traditional rubber tubes, as the chemical bond will fail.
