tube repair.

This is a legendary Olympic butyl rubber tube. These hold air! This one had the rubber valve stem torn off. It had been replaced with a stick-on rubber stem which was too short and had let go again on one side where the glue had not cured as it should.

I carefully removed all traces of the replacement stem and applied this thick truck tube puncture patch.

Then I installed a Schraeder 777 stem . The thickness of the puncture patch and it's wide footprint means there is plenty of rubber to clamp on and the stem has a nice wide foot.
I hope it works out. These tubes are worth the effort and I like a challenge. I even got all the photos to post, just out of sequence.

Here is a box containing Camel tire tube patches that I sold on eBay. The rubber patch trays sealed in plastic packages have cloth saturated with fuel that is lit and the and the patches are affixed to the leak using heat. Jim Patrick

I used to patch bicycle tubes with those. I don't know what they used in those heat "biscuits", but it sure did smell good, like the Fourth of July. It looked to me like the "biscuits" were some kind of fiber material with a little gunpowder mixed in. I used to have a clamp made to hold the metal things to the tube as the stuff burned off.

Fellows, vulcanising heat patches do not work at all well on butyl tubes. They are old technology for rubber tubes.
