KOM Cycling Tubeless Sealant Injector

I didn’t expect a huge amount from a syringe and a couple of pipes, but this is a really well thought-out bit of kit. This is better than pouring sealant into a tyre off the rim. It’s better than attaching some rubber tubing over the outside of your valve. As an added bonus to getting the sealant into your tyre without making a mess, it allows you to recover sealant via the valve to save the mess on changing tyres. The bonus of the aluminium valve tool (compared to cheap plastic ones I’ve had) is nice.

I used this with 'Muc-Off No Puncture Hassle Tubeless Tyre Sealant' which I understand is thicker than most with visible bits in (got a great review coming top in recent top10 test) and I was pleased I had no blockages when using the syringe (I didn't use the on/off tap just in case it got blocked and it works fine without). Easily fitted through presta valve after removal of core with supplied tool and avoided potential increased mess of over-valve tube provided with the sealant. All sorted in a few minutes and the washed out syringe and tube with water for future use. Hassle and mess free.

I recently used this to remove the sealant from my tyres before the tyre removal. Once I had put my new tyres on I used this to reinsert the sealant (the sealant was only a few weeks old so didn't want to throw it away) made the job of swapping tubeless tyres a lot cleaner, still not spotless though) Good quality and a few different tubes for going through the valve stem. May not work on the likes of Stans race sealant as this has much larger bits to seal larger holes.

The kit contained everything needed to top up my tyres with green goo. First time I've ever had to remove a core but the tool was very easy to use Rinsed of easily so ready for a refill in a few months

The idea is good. But don’t use it with sealant such as Peaty’s as the small glitter bits get stuck.

Actually does what it says. Good quality, and easy to use.

Makes the process of topping up tubeless wheels much easier as you can fill them up directly through the valve

Super easy to add and remove sealant without needing to unseat the tyre.

Facile da usare e di capienza sufficiente. Semplice anche la pulizia dopo l'utilizzo. L'ho usato e lavato più volte e la siringa resta a tenuta stagna. Provato con successo anche per latticizzare camere d'aria. Consigliato

The KOM Cycling Tubeless Sealant Injector Syringe is a great piece of kit for bike maintenance. If you you run a tubeless setup on your bike, this sealant injector will make the setup & maintenance easier & cleaner. The syringe holds 2oz (60mL) of sealant & has 2x 4.25in (110mm) sections of tube (3mm outside diameter) & a valve attachment for a total tube length of 10in (250mm) if you connect all. This is important if you are filling from a larger bottle of sealant & the fluid level is low. The tube fits both schrader & presta valves, just remember to remove the valve core. The set I purchased came w/the red anodized aluminum valve core tool. If you want this tool, be sure to choose it in the option when purchasing. The other option is a small plastic valve core tool. This plastic tool work just as well, I have one that I keep on my MTB, just in case. If you lose or misplace things easily, definitely pay the extra for the aluminum tool. The plastic tool is tiny, only a couple cm long. The aluminum tool is more than twice as long & the red anodizing makes it much more visible. This syringe is not a “must have” tool to go tubeless, but it sure makes it easier & less messy. I like that the tube goes through the entire valve stem into the tire, minimizing the amount of sealant inside the stem. This should help save on valve cores getting gummed up w/sealant. I’ve been using the syringe w/Stan’s NoTube sealant & it works flawlessly. After each use, I clean the syringe. I get a cup of warm soapy water, suck it up into the syringe & eject out 2-3 times. I then do it again w/fresh water for a rinse. This gets all the sealant out of the syringe & tube. I’ve been nothing but pleased w/the KOM sealant injector. Thank you for taking the time to read my review, I hope you found it helpful.

Works good with sealant application from the valve stem.

2 mal hat sich das Ventil mit der verwendeten Stans milk verstopft. Aber ging dennoch alles relativ problemlos

Produit super simple et pratique à utiliser. Aucun problème avec le liquide préventif de la marque no flats joes. Aucun éclaboussure. Ma technique : - Mettre la valve à 3h ou 9h (orientée ni en haut, ni en bas) - dégonfler le pneu en appuyant sur la valve jusqu’à ce que le pneu soit à moitié dégonflé puis utiliser le petit outil démonte obus fourni (l’outil rouge) et enlever complètement l’obus. - assembler les 2 tuyaux sur la seringue en intercalant le petit robinet bleu entre les 2 tuyaux (le tuyaux souple du côté de la seringue) - secouer la bouteille de liquide préventif - insérer le tuyau de la sereingue et tirer sur la sereingue pour aspirer du liquide - tourner le robinet bleu pour empêcher que le liquide ne retombe de la seringue (2 côtés bleus perpendiculaires au sens du tuyau) - insérer le tuyau dans le trou de la valve de la roue jusqu’à sentir que le tuyau touche la jante (la valve doit être toujours orientée à 9h ou 3h) - ouvrir le robinet bleu (2 côtés bleus dans le sens du tuyau) et presser sur la seringue gentiment pour vider le liquide - retirer la seringue - re visser l’obus - regonfler avec un compresseur ou une pompe à accumulateur de pression pour faire claquer le pneu. C’est vraiment facile et rapide en suivant cette technique et ça évite d’en mettre partout 🙂
