Bike retailers go through a lot of sealant, as tubeless tyres increasingly take over the bike world. Stan’s has just launched its OnTap sealant urn that stores and mixes a large volume of sealant to make the task of dispensing easier.
Stan’s OnTap looks suspiciously like a coffee urn, with a tap at the base to dispense tubeless sealant into an injector or measuring cup to add the sealant to tyres. But rather than coffee, it's designed for efficient mixing and dispensing of tyre sealant for bike workshops.
Because the particles in sealant have a tendency to settle out over time, there’s a motorised stirrer built into the dispenser, with a mix button that Stan’s says takes 10 seconds to get the sealant ready to dispense.
“A positive rider experience depends on evenly dispersed puncture-sealing particles throughout the sealant, which becomes difficult to maintain in containers larger than one litre,” says Mike Bush, Stan’s chief product officer.

The OnTap dispenser has the capacity for enough sealant for 80 mountain bikes or 160 road bikes. There’s a list of recommended volumes for different tyre sizes on the front of the urn.
Stan’s cites more precise sealant dispensing, better tracking of sealant usage and improved shop service margins as key benefits of the system for bike workshops.

Stan's sells 20-litre refills for the OnTap dispenser, which it says reduce plastic use by 75% over individual one-litre sealant bottles, as well as being a lot cheaper. It reckons the price of the OnTap dispenser is paid back after only 10 refills.
The OnTap dispenser is for sale to registered Stan’s dealers only, so you can’t buy one to put in your shed. Stan’s hasn’t advertised the price either.
