Park ToolTSI-1 Tubeless Sealant Injector(Return to Product Page)

When I decided to go tubeless I've never poured sealant directly into the tire, I've always mounted the tire and gone through the valve stem. This method has worked pretty well for me, I can't imagine pouring the sealant into the tire and then trying to complete the mounting to rim with it full of sealant especially with any hard to mount tire. I have a plunger-like product that I've been using but the Park Tool looks like a far better product.

Very easy to both measure and inject sealant through an open valve core with no muss or fuss. I really should have invested in this Park Injector instead of first getting Stan's version (which requires threading the tube onto the valve, a very messy process). This Park Tool is worthy of its price.

The injector works as advertised, and it is easy to clean once the job is done.

Now that all my bikes are tubeless staying on top of topping up sealant can be a hassle. I used to just unseat MTB tires but with tubeless road this was a little less ideal. Can easily top up tires w/out getting sealant near the valve stem. Also if you clean it right away prob takes 30 seconds max to clean, very easy.

I paired this with the Park Tool Wheel Holder in order to service my tubeless tires. Remove the valve core and easily check the sealant level and then measure while drawing up out of the bottle and see the exact amount on the Injector. Put the tube through the valve and inject the sealant. This is the cleanest method I have used. The Injector cleans up easily in the sink. Quality build will last my lifetime.

Besides my bike stand this is prob my 2nd or 3rd favorite tool now. Good gravy, too easy with the Orange Endurance. Appreciate the excellent pricing and near instant ship from BTDirect!

Makes your periodic refreshing of sealant much easier than any other method. Easy to measure and then to inject into the tire through the removed valve core.
