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

Using the OKO tyre sealant was easy peasy. You start off by removing the yellow stopper which has a valve core removal tool, carefully you unscrew it and allow the air out the tyre and then place the tubing over the valve, you then squeeze the required amount inside the tyre and then replace the valve core and inflate to correct PSI. I use OKO on my tractors and it works great as sometimes they get punctured by a screw or nail in the farm yard. This time though, I needed a fix for my 2015 polaris ranger diesel UTV that is used for farm work so it sees a lot of off road use (and some on road) that had a slow puncture and this tyre sealant fixed it no problem, so it works also on older tyres and not just brand new ones as it says on the label. Have since put it in the other tyres to get peace of mind. This stuff just works and highly recommend it.

Very good, easy to use and fixed all 4 of my lawn tractor tyres with 1 bottle

This is weird looking stuff, it looks like runny grey porridge, but it did a great job on sealing the blackthorn puncture on the 15x6x6 front tyre of my Mountfield garden tractor mower. Very clear instructions on the bottle on how to use including dosage rates for various hub/tyre sizes. Mine used 250 ml from the 1250 ml bottle, so I added another 250 ml to the other front tyre too. Whole process only took about 15 mins. The blackthorn puncture was successfully sealed by the fluid and tyre pressure was maintained. I can't bear witness to how the fluid will perform over time, but first impressions are that it will save me a load of money in puncture repairs going forward.

I have used this before and it is very good, shaved me a lot of punchers in my ride on mower.

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.

This is an excellent product that works well. I ended up using it on all four tyres of a ride on mower as I was constantly previously getting punctures from Hawthorne and Blackthorn hedges. Not had any problems since, and also used it successfully on a little trailer.

I have used this sealant in my off road Quad bike, a topper and a garden trailer. We have a small holding and I have to be able to take this machinery over quite rough ground. So far so good. A small puncture on the topper, probably caused by a thorn quickly sealed and has held since. Very handy having a valve core removal tool built in to the stopper top. The bottle is well marked for measuring the sealant amount accurately. This sealant is for tubeless tyres, not tubed.

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.

ottimo e fa rispiarmare le riparazioni. L'ho provato sulla ruota posteriore dello scooter che ogni settimana mi andava giù la metà della pressione da 2.2 a 1.2, dopo aver messo questo prodotto non mi è più calata. Ottimo.

Usado en ruedas delanteras de un tractor llevo meses sin tener un solo pinchazo, trabajando en campo. Buen producto

Très satisfait ! Enfin un bon produit qui empêche la crevaison à chaque sortie de ma tondeuse débroussailleuse ! 200 ml dans chaque chambre à air des 2 roues agraires et ça passe sur toutes les épines noires et ronces sèches sans conséquence, un vrai plaisir destructeur ! J'ai même pincé la chambre à air en la remontant, elle s'est donc dégonflée, mais l'adjonction du produit puis le regonflage ont comblé ce 'pincage' et ça tient depuis plusieurs semaines.

It’s excellent

Produit stupéfiant. Suite à l'achat de pneus de tracteur BKT bas de gamme et en usage pro, beaucoup de crevaisons. Plus de souci avec ce produit. Plus d'immobilisation. En plus le produit est simple à appliquer soi même et on gagne beaucoup de temps (en plus de l'argent) par rapport à une réparation classique par rustine ou champignon. Le produit colmate tellement bien qu'il est capable de boucher la valve en l'absence de l'obus. Par contre il ne semble pas fait pour polymériser, il contient seulement beaucoup de fibres et particules qui viennent obstruer les trous. J'en ai mis 1/4 de la dose prescrite (quand même plus d'un litre) et çà m'a suffit pour les deux pneus. J'avoue que je ne comprends pas le commentaire négatif à propos de la trotinette. Est ce bien le même produit dont on parle ?
