A pump head configured to secure various air valve types is disclosed. The pump head may include a housing and an interior unit sized and shaped to receive a valve head. A moveable pin disposed within the housing coaxially with the first axis may define a pin notch disposed about an exterior circumference of the moveable pin. A first taper unit may be disposed in the housing coaxially with the first axis and coupled to the pin return spring. A second taper unit may be disposed in the housing coaxially with the first axis and adjacent to the first taper unit. An elastic taper C-ring may be disposed between the first and second taper units. A lock arm may be configured to engage the first taper unit with the second taper unit, thereby compressing the elastic taper C-ring circumferentially in one of at least two positions, the elastic taper C-ring compressed about the pin notch in the first position and about the valve head in the second position.
