Description
The Hold Fast Tubeless Sealant Injector, AKA The Xfer’r, is the ultimate sealant tool. The Xfer’r (pronounced transfer-er) can be used to add or transfer tubeless sealant from tires.
Simply slip the hose onto any Presta valve with the core removed and pour in the desired amount. Press down on the plunger and you’re done. If the sealant will not flow, that means your valve is clogged and needs to be cleaned. Regardless of what brand of sealant you use, if it does not flow easily into your tire, you need to clean your valves.
To transfer old sealant, this is where you want to use the Tubeless Sealant Injector as a vacuum syringe. Pop one bead off your rim, and suck up the remaining sealant. Swap tires, then add the sealant to your new tires using the instructions above.
We suggest using 1.7oz (50ml) of sealant per 1″ of tire width. Need some sealant, check this out.
The Hold Fast Sealant Injector only works with Presta valves.
