Park Tool Glueless Patch Kit
Park worked with 3M to produce a self adhesive tube patch that stretches, flexes, twists, and turns right along with the tube and they came up with the Park Glueless Patch Kit GP-2 . No messy glue, no bulky packaging. Lightly roughen tube with the included sandpaper, clean, apply patch, and you're ready to go. Six Park Glueless patches with sandpaper in a neat little carry along box.
Quick, easy to use, light weight to put in the pack! They get the job done and back on the trail!
Swear by the Park Took glueless Super Patch. Some years back we had our first try with them and had poor success. It only took 1 ill fated try to determine that preparation of the surface of the tube around the puncture was key. You need to rough up the surface extending past the outside of the patch size. It needs to be totally dull. If any mold seams are in the patch area, they need to be leveled to the surface of the repair. We cut extra swatches of sand paper from large sheets in the shop to insure that we have enough sanding material on hand. Now that we have this process down, the patches are always successful. They bond to the rubber so well that you can actually stretch the tube and the repair stretched with it with absolutely no delamination.
These patches are super easy to apply and in my experience, a permanent repair for most small punctures. The kit weighs next to nothing so there's no reason not to keep it in your bag. For larger holes or cuts, traditional glued patches are more likely to be the better long term solution, but you can't beat the convenience of these glueless patches.
After sanding a spot with the little pin hole on the tube, I tried putting the patch on the tube, only for the air from the pin hole to eventually push through the cheap glue on the patch. This leakage occurred despite the fact that I held the patch in place firmly for over a minute on two different tries.
I stopped using glue on patches over 15 years ago and never looked back. Park are the best of the glueless patches on the market, one reviewer said his dried out after 6 months, I've had as many as 13 patches on a tube and the oldest patch was 4 years old and still holding and the tube was a primary tube! Some people don't like these but that's because they don't know how to prepare the tube correctly, you have to buff the tube in an area larger than the patch will cover first like you would with a glue on patch, then you press the patch on as hard as you can between your fingers and thumb for 30 seconds and repeat on each corner; then look at the patch, if the patch has a frosty looking area press that area again and it should go away. Word of warning, these patches will not work well on latex tubes, they will hold about a week or two then let go.
These patches are quick to apply, weight almost nothing, and take up no room in your pack. Superb quality from Park as always.
Super quick patching. Holds bond for life of tube
These are light, quick and cheap. I have a couple fail when they dry out, but that's 6 months later.
Comes in a sealed plastic bag, which is awesome if you ride in the rain alot. Works great, no glue needed. Pull the tube, find the leak, scuff it up with included sandpaper, put on patch. Trick is not getting any of the crap on your fingers on the glue - peel it from the edge and apply it like a band-aid, only touching the backing. If you get all the air out of it and get it in the tire right away it works great. I've had one in for a month or two and no problems.
I have found this to be good for a quick fix but doesn't seem to last as a permanent fix. I am still going to use this product to get down the mountain if a flat occurs.
no reason to go with any other patches. 1) find the puncture. 2)sand the spot with the lil sandpaper square the kit comes with. 3)clean spot. peel n stick patch. press firmly so theres no air bubbles. 4) inflate tube and get rollin
