I like this little funnel. Makes putting in sealant a breeze.
Really way to use. I like it better than syringes and tubing. The one thing to “watch out” for is that some valve stems don’t have threads on the top for this to screw into. It’s still possible to use this (just hold it down on top of the valve, might make a tiny mess) but it isn’t quite as nice as when you can screw it on
Thanks Matthew! I have a new model available that works with valve stems that are not fully threaded: https://strazcomponents.com/products/sealant-funnel-pt-orange
This has been a super helpful, time-saving tool! The only caveat is for Specialized tubeless valve stems which are not threaded all the way to the top. The threads are down lower on the stem, so you can't thread it on. If I hold it in place, it will work, though.
Thanks Mark! Take a look at the new Sealant Funnel PT model, which works with valve stem threads that sit lower on the stem.
compact, easy to use, easy to cary, simple. my only wish is that the funnel had visable label of how much volume it held for ease of knowing how much fluid to put into the tube.
Thanks Vladimir! Each funnel has a label on the inside showing it holds up to 30ml.
I ordered one of these funnels as soon as I read the review on Bikepacking.com. I received it very quickly, and I have had the opportunity to use it once. It really is a great accessory. After my initial use, I already prefer this over my Stan’s sealant injector(older model). With proper use, I feel like this funnel should last a long time.
A couple funnel-fulls were all I needed to top-up my wheel. It worked flawlessly and with far less mess than an injector. I’ve found that with the injector I usually get some dripping when the syringe is removed. There was not a single drop of sealant dripped when using this funnel. The quick procedure was to remove the valve core/let air out of tire, thread on the funnel, shake and pour a near but not completely full funnel volume, let the funnel empty into the tire, slowly roll the tire a bit to get the sealant to finish “gurgling” into the tire. Again, I did this twice with no drips. I also feel that cleanup was very easy and wasted almost no sealant at all. There is very little sealant that remains adhered to the funnel, as opposed to what you’d normally have to wash from a syringe set-up. I highly recommend supporting Straz. Get yourself one of these!
