We don't throw the word ultra around lightly! Comfortable, durable and most of all reliable, our Ultraflate is our most tried and true cupped inflator. Its reinforced glass nylon construction and brass internals means it can take the strain of everyday use and still maintain precision inflation performance. Trigger-controlled technology for fast, easy and controllable CO2 inflation. Built-in “trigger lock” to prevent accidental discharge. Heavy-duty design and construction. Works with both Presta and Schrader valves.
