Oumers Bicycle Puncture Repair Kits, 15 PCS Self-Adhesive Patches with Rasp

Puncture repair is a very important aspect of the riding process, especially when you have a puncture more than ten kilometers away from home, as it can bring about a lot of inconvenience. This requires you or a friend accompanying you to carry a puncture repair tool. A tire repair tool is a consumable item, and our patch is a great addition to your kit.

Patches with glue will work just fine, but considering that carrying glue around can be inconvenient, and the fact that glue can easily leak from squeezing, which can cause your bag to stick, it may be preferable to use a glue-free patch. After you patch a tube, the glue starts to dry in the tube, making the process less than ideal. When you're patching punctures on the road, you'd better have patches that don't require glue, so we've developed this convenient, glue-free option.

The instructions for using our glue-free patch are as follows:

1. Completely deflate the inner tube after finding the puncture point.
2. Grind the edge of the hole into a new surface with a metal file first. The polished area should be slightly larger than the size of the tire patch. At this time, the puncture point should be in the center of the polished area, and then ensure that the polished inner tube is free of foreign matter, water stains, and oil stains.
3. Place the patch on the fitting surface of the inner tube properly and press it for 1 minute. Avoid air bubbles or wrinkles during the operation.

Regarding the possible reasons for some failed cases:

1. If the surface of the inner tube has not been properly filed, the patch cannot be bonded to the old surface, and there may be a gap between the adhesive surfaces without the necessary pressing of the patch.
2. If the hole center of the inner tube deviates from the center of the patch, the force of the patch on the air pressure generated by the hole may be uneven, causing the patch to open a gap for the airflow.
3. If the new surface after grinding has stains, water stains, grease (especially oil stains, which can ruin a patch), or foreign objects, it may be related to the air environment and can affect the effectiveness of the patch.

By following these instructions and understanding the potential pitfalls, you can ensure a successful puncture repair using our glue-free patch, which is a convenient and reliable solution for your riding needs.
