The Park Tool TSI-1 Tire Sealant Injector completely changes that. It’s simple, clean, and makes the whole process take less than a minute. The injector comes with a long hose that fits snugly onto Presta valve stems (after removing the valve core). The syringe is large enough to handle a decent amount of sealant in one go, so no more spilling from trying to pour directly into the tire. Quick How-To: 1. Remove the valve core with a core tool. 2. Measure out your sealant in the injector. 3. Attach the hose to the valve stem. 4. Slowly push the sealant in. 5. Reinstall the valve core, air up the tire, and spin to distribute. That’s it—no more mess on the floor, no sealant sprayed all over the rim, and no wasting product. Pros: • Clean, quick, and accurate way to add sealant • Works with both Presta and Schrader valves • Durable build quality (typical Park Tool) • Large syringe capacity Cons: • Hose needs a quick rinse after use to prevent sealant from drying inside • Slightly more expensive than generic injectors, but worth it for the quality Overall, this is one of those tools you don’t realize you need until you try it. If you run tubeless, the TSI-1 pays for itself in saved time and frustration after the first use. Review: Must-Have Tool for Tubeless Tires - The Park Tool Tubeless Sealant Injector is an absolute game-changer for anyone running tubeless tires. This tool makes the messy process of adding sealant much easier and cleaner. The large capacity lets me load up enough sealant for multiple tires, and the nozzle fits perfectly into both Presta and Schrader valves without any leaks. Ease of Use: The design is simple and effective—just fill the injector, attach it to the valve, and squeeze. I can get a precise amount of sealant into the tire without spilling everywhere, which makes tire maintenance much quicker and less frustrating. Quality and Durability: It’s built with quality materials that can withstand repeated use. The clear body also allows me to see how much sealant is left, which is a nice touch for tracking usage. Pros: Easy to use, mess-free sealant injection Large capacity for multiple tire applications Durable and well-made Works with both Presta and Schrader valves Cons: Might be a little overkill for single tire applications, but perfect for frequent tubeless users If you’re tired of using makeshift methods to add tubeless sealant, the Park Tool TSI-1 is definitely worth the investment. It’s simple, effective, and a real time-saver. ## Features - Easy-to-use syringe-style injector for setting up and removing tubeless bicycle tire systems without making a mess - Injects sealant directly into mounted tubeless tires through the valve stem without removing the bead from the rim - Long, thin tube fits all the way through most Presta stems with removable valve cores - Oversized syringe body with easy-to-read gauge for precise application of sealant - Holds up to 100 cc (3.5 fl. oz.) of any injectable tubeless sealant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097F1XV7D | | Best Sellers Rank | #25,912 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #53 in Bike Shop Tools | | Brand | Park Tool | | Brand Name | Park Tool | | Customer Reviews | 4.8 out of 5 stars 647 Reviews | | Included Components | Power tools | | Item Type Name | tools | | Item Volume | 100 centiliters | | Item Weight | 100 g | | Manufacturer | PARK TOOL | | Material | Plastic | | Model Number | 4003113 | | Number of Items | 1 | | Part Number | TSI-1 | | Sterile | Non-Sterile | | Sterility Rating | Non-Sterile | | UPC | 763477008275 | ## Product Details - **Brand:** Park Tool - **Item Volume:** 100 centiliters - **Material:** Plastic - **Number of Items:** 1 - **Sterility Rating:** Non-Sterile ## Images ![TSI-1 - Tubeless Sealant Injector, One Size, Blue | Park Tool Tubeless Sealant Injector - Precise 3.5 oz. for Tubeless Tires - Image 1](https://m.media-amazon.com/images/I/61tAnbPsXKS.jpg) ## Questions & Answers **Q: For practical purposes how is this different than a $5 turkey injector syringe (@ 1/5th the cost)?** A: I'm all in favor of generic solutions, but most turkey (marinade) injectors like the $5 one from Walmart only hold 1oz, and not sure the needle would be small enough to fit inside the valve stem **Q: Will this work with Stans Race sealant? The race sealant seals the injector tube before it gets into the tire with my other injectors.** A: Stans race sealant clogs this park injector. Really really clogged. The crystals are too big to get any flow into the plactic injector tube. **Q: Mine arrived inside a zip lock bag, coated in some sort of clear lubricant. Is this normal or did I receive a used product?** A: Mine arrived the same way. I emailed Park Tool and the packaging described is how they are now shipping the product. The rep mentioned that there can sometimes be excessive lubricant applied to the o-ring and to simply wipe everything down. The rep assured me that once wiped, the remaining lubricant will not affect the sealant. **Q: I need replacement needle/tube. Where can I get it?** A: I would contact Park directly; their customer service has always been excellent in my experience and they are pretty good at stocking replacement parts for their tools ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must-Have for Tubeless Setups *by P***L on September 23, 2025* I’ve been running tubeless for a while now, and adding or topping off sealant used to be a messy chore.
