Silca's Ultimate Tubeless Sealant Replenisher can be used to extend the life of your Silca Ultimate Tubeless Sealant by up to a year. Environmentally safe, with a natural latex formula and no ammonia, it should be used every 90 to 120 days to keep your sealant functioning at its best.

Available in either a 4oz or 32oz bottle, it can be injected through the valve stem thanks to the included rubber hose and injector cap in the smaller bottle and the ability to either use an injector cap with the larger bottle or use it to refill the 4oz bottle. Alternatively, the large bottle can be easily and cleanly decanted using the Silca Ultimate Tubeless Sealant injector.

Either way, it is effective down to 0°F/-18°C and can be used on a schedule of 1oz at three months, 1.5 oz at six months and 2oz at 9 months, assuming a 23-30mm tyre, to boost the sealing power of the sealant back to race day levels with longevity.

This replenisher is your talisman for confidence and will help you to avoid large maintenance of your tubeless tyre sealant for as long as possible.

Sachet Instructions

1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.

2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation! 

3. Carefully cut one corner of the sachet open along the diagonal cut lines.

4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this. 

5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!

6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it! 

7. Go clean that filthy bike!
