OKO Off-Road Tyre Sealant 1250ml – Heavy-Duty Puncture Protection for Tractors & Industrial Vehicles – Seals Up to 12mm – Mess-Free Cap – Long-Lasting, Non-Corrosive – Tubeless & Inner Tube Tyres.

Good service for good product

Ideal for garden etc equipment with pneumatic tyres. Can be used to repair punctures as well as prevent them. Fit to the inner tube (full instructions and all items needed to do so are included, tube, valve remover / replacement tool), inflate with the puncture at the bottom and you'll hear the leak suddenly stop as Oko is forced into the hole. If less obvious, fit the sealant and inflate the tyre, then spin the wheel to coat the puncture-prone tread area. The 1250ml bottle will treat a lawn tractor and a few wheel barrows etc. It you have several karts, barrows etc, 2 bottles will treat most normal humans' potting sheds and leave some for future needs / top-ups as necessary. Don't be without some! Using Oko is a lot easier and far quicker that struggling to extract the inner tube, patching it and then struggling to replace it and re-mount the tyre without pinching it and creating another hole, just when you really want to be using the barrow etc you've pulled out from its resting place, only to discover it's not usable because of a flat!! Highly recommended.

I have been renovating/restoring an old trailer to tow behind my mower. The trailer sat for 10+ years and the tyres were basically rotten and had large cracks. They didn’t hold any air at all. I bought this stuff as a test because the wheels are so rusted on I can’t get them off. I was expecting very little result purely because the tyres were so damaged. To my amazement I put this stuff in and the tyres took air and held it!! One tyre is perfect and holding pressure, the other has one area with quite a wide crack that is letting small amount of air out. Planning to seal it from the outside with liquid rubber. This stuff is amazing! The bottle had just enough for 2 small 13 inch trailer tyres so if using for a ride on lawnmower or ATV you’d probably need a couple of bottles. Worth every penny though.

Easy to use if you get a valve extract tool.I thought it came with valve tool it didn't. But I got one for about£2 I thought I'd need help as my dexterity is limited but even I had this sorted in under 20 minutes with a single barrel foot pump ..and I use my hands,worth doing I think,wouldn't want mobility scooter miles from home with puncture 1st day I took it out its fat wheels got one ,luckily I noticed coming back nearly home,so I just kept going.feel more confident after using this product.even tho I haven't made a really close inspection to see if its working.more secure feeling good enough.you never know when its about to get mad max ,when your out on the mobility scooter.keep Rollin.😂

I'd originally put Goop puncture repair in my sit on mower tyre, which had stopped working, despite its "life long" guarantee. So decided to risk putting OKO in the tyre as well as the no longer effective Goop already in there. Just checked the tyre and it's still fully inflated, using 300mls of OKO. So no need to take the tyre in for puncture repair. Most impressed.

Had 2 puntures on my hyper scooter used this boom solid tyre no loss of air and peace if mind absolutely fantastic product please shake very well foe best performance I mean a good 5 mins...200miles after still at 50 psi no leaks wow amazing...209% recommend

The bottle is the old type, but does include a valve tool inside of it. It’s not too obvious until you remove the tube plug! Hopefully it seals my puncture.

********* UPDATE NOW AFTER 1st REVIEW BELOW****** after 3 weeks i have took the wheel off to put more air in tyre it has worked and stayed up great . it has stayed a liquid like in the bottle after 3 weeks in the tube . so spinning after putting in is not so important as it stays a liquid .but you would still need to reach the puncture area initailly***********IF YOU CAN'T SPIN THE WHEEL AFTER FILLING THEN NOT MUCH CHANCE OF FIXING PUNCTUREI followed instructions but did not seal . not sure if i put enough in . ALSO NOT SURE ON HOW LONG IT TAKES TO COMPLETELY SEALBUT THIS IS HOW TO USE...SHAKEWITH STANLEY KNIFE CUT HALF WAY DOWN VALVE REMOVERREMOVE VALVEPOUR IN MIXTURE BY PUSHING HOSE OVER VALVEIF POSSIBLE SPIN WHEEL SEVERAL TIMESSCREW BACK VALVE ONBLOW UP TYRE TO HIGH PRESSURE . THEN SPIN FOR A MINUTE. THEN CHECK NEXT DAYTO STOP HOSE GOING BACK INSIDE USE CABLE TIE AROUND BASE . COVER TOP WITH VALVE EXTRACTOR
