The ENVE Presta Valve Air Chuck features a simple and adjustable locking mechanism that secures the pump head to the valve stem while depressing and opening the valve simultaneously. This process prevents air from leaking and ensures accurate pressure readings. Constructed from stainless steel and aluminum, the ENVE Pump Head is ready for a lifetime of inflation duties.

• Presta Valve Air Chuck is manufactured by KCNC and fits rubber hoses standard on most floor pumps
