The Giant Tubeless Sealant Refill & Check Syringe is a tool designed for maintaining tubeless tire systems. It allows you to easily check the sealant level and refill it without making a mess3.
Key Features and Benefits
- Clean and Easy to Use: The syringe helps to avoid spills and mess when adding or removing sealant13.
- Accurate Measurement: The syringe is graduated, allowing you to measure the amount of sealant being extracted or injected. It can hold up to 60ml of sealant13.
- Valve Adaptor: Specific injectors usually include a valve adaptor that makes the job easier1.
- Versatile: Suitable for various types of bikes, from pro-level race bikes to fitness and adventure bikes4.
How to Use
- Remove Old Sealant: Unscrew the valve core and insert the rigid straw through the valve to the bottom of the rim. Suck out the old sealant using the syringe1.
- Measure: Check the amount of sealant you have taken out using the mL graduations on the syringe1.
- Refill: Insert the straw again and squirt new sealant in1.
Additional Tips
- Some people prefer to inject the sealant through the valve, while others pour sealant into the tire before finishing the installation1.
- If your wheel doesn’t have tubeless-ready rim tape installed, you will need to tape the rim with tubeless-compatible tape1.
- It’s normal to need to top up sealant occasionally to ensure there is enough to seal any punctures
