Slime Tube Sealant
SLiME tube sealant prevents and repairs flats caused by puncturing objects up to 1/8" (3mm). SLiME works repeatedly and is non-flammable, non-toxic, non-aerosol, and cleans up with water and lasts for up to 2 years.
SLIME can be installed as a pre-treatment before a puncture occurs (low speed only). SLiME can also be used to repair a flat tire or a slow leak - simply remove the valve core from your tire, inject SLiME, re-inflate and rotate it.
After removing the valve core, SLiME is squeezed into the tire through the valve stem. Once installed into the tire, SLiME remains liquid, evenly distributed by centrifugal force. When a puncture occurs, the escaping air forces SLiME with Fibro Seal technology in the puncture wound to seal the puncture.
The Slime chemists have developed a state of the art system of environmentally friendly fibers, binders, polymers and proprietary congealing agents that intertwine and clot to seal punctures up to 1/4" (6mm) in tubeless tires & 1/8" (3mm) in tube tires.
This Fibro Seal lattice, together with the viscous transportation system, seeks out and tightly packs itself into any puncture area, preventing and repairing flats with a flexible long lasting plug.
Winston G should not have given a 2 star rating for using a product outside of its intended purpose. This is indeed tube sealant and not generally intended for use with tubeless tires. It can sometimes be mixed with tubeless sealant in the hope that the included bits of ground up rubber in the slime solution help with sealing various-sized holes, but it is not a standalone tubeless sealant solution. As a tube sealant, however, it is phenomenal. And as a mechanic, myself, I love it and recommend it. I use it on my own commuter because it really does help prevent flats. It also reduces the frequency with which I need to inflate the tubes. Standard inner tubes are fairly porous and loose air over time. Tubes with slime in them that get shifted on a regular basis are sealed from leaking and can hold a consistent air pressure for months. It is indeed messy when you get a bigger tear in the tube, but the infrequency of this weighed against the frequency with which I get flats without it tips the scales in favor of slime.
I had a tubeless tire with a slow leak and put in some of this slime thinking it would be all good, but after 24 hours and a lot of slime, it didn't plug up the leak. Still lots of tread on the tire, so still riding it with a tube, but wished the slime did the trick. the bottle does say "tube sealant" but the PP description does mention for tubeless tires so I think I bought the right thing...
Pretty simple to use, just make sure you read all the instructions so you don't make a mess of yourself or the floor. States its useful life is 2 years once installed. I have seen slime filled tubes peppered in thorns that finally gave out after hitting a large nail or piece of glass. Riders love it, mechanics hate it. Overall a good buy.
