Collection: Valve Core Removers — Straz Components

Love it!

Excellent product

Easy to use product!

Great idea. Depending on the sealant you may need a valve stem rasp to clear clogs at the bottom of the funnel

Works great for my specialized tubeless valve stems!

WORKS GREAT!

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)
