patch plug techniques

[artieb]

What are the do's and don'ts? Do I use the usual patch process? I see different products and what is the best for general repair? I have patched for years and is this really the new deal?
Thanks Artie

Um... sorry, but what exactly are you referring to as a "patch plug?"

This term can refer to an electrical test plug, a tire plug, a sheetrock patch, or a host of other things.

In the uk we have been using a patch with a plug for years, you drill the hole, with a bur bit in effect, approx 7.5 mm use the adhesive on the tire remove the backing from the patch plug, as you would with a patch then pull the plug through the hole

Look up techtire on youtube. There is a short video that covers everything.

Shooting from the hip and distant memories of tire school years and years ago. The only things that stuck were: clean, clean, no fingerprints on the sticky parts under the blue plastic, rough up the tire inner surface, again super clean. Look at the angle of puncture, if 30 degrees or less, use a two piece patch plug for a better seal and smear black goo around the edges of the patch part for an enhanced seal.

Drill the hole out to slightly under the plug size. Rough up the tire where the patch part will sit, I have used a dremel tool in the past, it works well. Scrape the roughed up area to get anything that is left on there off. You can buy a tool for this or just use a gasket scraper. Clean everything like crazy. I mean, scrub it with soap, wash it off, brake clean it, get it super clean. Rubber cement (the stuff the parts store carries for it is the same stuff that staples has) on the tire where the patch will sit, rubber cement on the patch, stick them together. Get one of the stitching tools that the parts store has by the patch/plugs. Run it over the patch/plug repeatedly in different directions. Using that stitching tool will ensure a good seal.

The stitching tool looks like this:

stitching is a must

Just dont be like my co-worker and think that you are "vulcanizing" the rubber by smearing glue over the hole and lighting it on fire....

Almost a perfect reply. Only thing to add is you put the rubber cement on both surfaces and let it dry, then you put the plug in, rubber cement is a "contact" adhesive. The stitching part is very important. Do it 2or 3x more than you think you need to. Keith

I gotcha I have done some Internet research and everything was precision, and requires 3 additional products, besides the rubber cement. I have put on tire patches for many years and have had better than average results. The cleaning, roughing up, and stitching is the same? The only other step would be to ream the puncture, like a tire plug?

 

[IFMJohn]

The only extra step to a plug patch is to ream the hole.

I ordered 30 of them. I already have a 1/4" carbine reamer, I'm in the tire repair business! Thanks Artie

Oh and when you finish, cut the end of the plug off so it is flush with the tread.

when you remove tire from rim if there is a lot of black powder inside or evidence of sidewall pinch / run on flat DO NOT repair the tire . . .

I never had good luck with them. The rope type plugs I have had good luck with but I made it a point to NEVER EVER EVER repair a tire that had a hole near a sidewall. We used to plug the work truck tires and the plugs would be in there for alot of hard miles no issues.

 

[rwelch]

look up rubber manufacturing association and find tire repair tab for guidelines

I never had good luck with them..

I'm not trying to be a **** (but I will sound like one), but it was most likely operator error. They're no harder to install than a regular old patch, except for the step of reaming the hole.

I've installed hundreds of tire repairs during my days in the tire shop in college. I've installed rope plugs, patch plugs and plain patches.

I'm not one of the rope-plug haters, in fact I still install them myself at home. But the modern patch/plug is the "correct" way to repair a tire according to the Rubber Manufacturers Association, the tire industry's trade group.

+1 seen the rookie tire guys do this once or twice BIG boom
