Slime 10003HT 237ml Inner Tube Sealant

The `Slime' inner-tube sealant offers prevention as well as repair for small tube tyres (i.e. bicycles, dirtbikes or wheelbarrows). The idea is simple - the bright green slime substance is injected into the insides of the tyre's inner-tube, which then coats the whole interior of the inner-tube via the centrifugal motion of the spinning wheels. Once installed into the tyres, the slime will seep into any small holes that appear (or are already present) in the inner-tube, and solidify within the hole, plugging it before any further air can escape.

The slime is continuously in motion within the confines of the inner-tube, allowing it to always be ready to seal any new punctures that appear. The slime will repair punctures which are up to 3mm (1/8 of an inch) in diameter. Obviously the offending protrusion that caused the puncture should also be removed, if indeed it is even noticed!

Having fallen foul to a number of small punctures during my daily commute (of which a portion is through hedge-lined lanes), I decided to give the Slime a whirl. To be honest, the concept seemed too good to be true. As long as the punctures are relatively small (i.e. thorns from pesky hawthorn bushes), we're told the slime will locate and plug the puncture with minimal deflation of the tyres. Once plugged, the puncture is as good as fixed! Really? I decided it was worth a try at least.

The application sounded a little daunting for an average-Joe non-bike-expert. The directions on the back of the bottle tell you to "remove the valve core from inside the tire valve system" using the clever little tool that comes supplied with the bottle (and which doubles up as the lid). Believe it or not, but this really is a doddle to do. Just pop the little plastic tool into the valve, twist it anti-clockwise, and the valve core just unscrews out. A great start!

For bikes (such as my mountain bike), you need to use 4 fl oz's of slime per tyre. This bottle contains 8 fl oz's, so it's half the bottle per tire...simple! Using the little flexible-plastic tubing that's supplied, you just squeeze half the contents into your now very flat inner-tube. When that's done, screw the valve core back into the valve using the little plastic tool again. Now, re-inflate your tyres to the desired pressure (usually noted on the tyre itself). Once this is done, all that's needed is a quick spin of the tyres to spread the slime around and hey presto - job done!

Now then, the main question... does it actually work? Well, previously I suffered from small punctures every couple of months or so (during the summer it's worse because the hedges are often trimmed back and thorns end up everywhere). Since applying the slime (almost 5 months ago) I haven't fallen foul to a single puncture. Is this proof of the products ability? - not 100% scientific proof, but it's good enough for me.

The bottle's label states that it's guaranteed for 2 years after application. Two years of protection from 5 minutes of work injecting it into the inner-tubes...incredible! It's only been 5 months, so I can't really comment on the 2 year claim, but so far, so good.

I knocked out a video of the application process to show how very simple it is to do. Slime is also available for tubeless tyres, as a tyre liner, or as pre-injected inner-tubes (none of which I've tried).

This is an excellent product.
We had a puncture on our Jane pram. All I had to do was squirt this into the tyre and pump it up, no more puncture. I did the other 2 tyres as well in case they get a puncture in the future.

I brought this product for my pushchair tyres as I was constantly getting a flat tyre on one wheel. Since buying and using Slime the problem has not reoccurred. My toddler and I can now go for long walks in the country without the worry of getting a flat.

A must have product for all pushchairs with pneumatic tyres.
