You're looking at a mighty tubeless valve. It seals well to the rim and, since it's a presta valve, it has a removable core so that you can clean it when its inevitably become blocked by overambitious tyre sealant. At 46mm long it fits even reasonably deep carbon mtb rims.

Not only a decent valve, it can be used with tyre inserts because of it's t-shaped air passages. It also has a hex slot at the base also allows you to hold the valve still, just in case you ever need to (valves can get rather slippery). We're not quite sure why other valves, like Cushcore ones, retail for $50 plus per pair - it seems a bit steep. 

Note: This is one valve, if you want to purchase a pair you will need to purchase two... Math 🤓
