I use a Topeak Smart Head which fits Schraeder and Presta valves You can also buy the head only.
Don’t get sealant inside it as it bungs up the works!
I don’t recommend the Topeak Twin Head as the Schraeder side doesn’t have a plunger that presses the valve pin inwards. Without the pin you are unable to bleed off air with the airline connected (assuming your gun has a bleed off valve).
