Collection: Sealant Funnels for Tubeless Tires — Straz Components

No mess, no fuss and simple to use. I've purchased four so far and given several to my friends as these little funnels make for a simple sealant fill in the shop or on the road. Just plain works great! Great colors too!

This is the best way to add sealant to a tire.

Works great. So much less mess. Feels a tiny bit more expensive than need be, but this will last me the next 30 years, so maybe not. I definitely needed the version that works on WTB valves, good call!

Fast and easy way to replenish sealant without all the mess and easy cleanup. My wife prefers this method over using a syringe.

Hack: squeeze the tire before filling the funnel and release once it’s full. This help create negative pressure that draws the sealant in quickly. The funnel is about 2oz., so you can use that to determine how many fills you need.

Great funnel for a clean fill and top off of sealant. Much easier than a syringe or popping a bead for sealant filling. No more sealant dripping on the floor.

I can't believe how easy this is to use and clean up. I used to use a syringe and cleaning it took some time. The funnel can't be any easier and this took much less time than either popping off the bead or using a syringe.

So easy to use and is the best way to add tire sealant without the mess

The Sealant Funnel is probably the best way to add sealant to a tire. Removing valve core, threading funnel onto outer thread, and then pouring sealant is much simpler than my previous method of using a syringe injector. No more "burps" or sealant mess. Small enough to carry in my bike kit. Highly Recommended!

(Full disclosure: Tim sent me a sample Schrader funnel to test before production)

This is the handy little item that I didn't know I needed until I used it. I previously would hook a syringe and tube to the valve stem and dump in the sealant (without using the syringe plunger), but the tube often slipped off -- plus it was difficult to keep track of the volume of sealant that went into the tire. When using this tool, I can fill to the 30ml mark and the fluid will remain there for a second, so I can keep track of the amount. (I typically use 90ml, so three quick fills.) With this tool there is no spilling and no mess to clean up! Highly recommend.

I saw this at a local shop. I immediately bought one and took it home. After I topped up all my wheels with it, I bought 3 more (two gifts and one extra for me.) It works. I have not tried it with Silca's NEW sealant. I used it with OrangeSeal Regular and Endurance. I like that one "funnel" is about 2 oz.

Nicer application for sealant into tire!

Simple and effective. No more mess.

We got a couple of these for the shop (Munroe Velo, Topsfield, MA) - they work so well i ordered one for home use as well. Thanks for a great and simple product!

This is just what I was looking for to make tire sealant a breeze!
