Abstract
A manual air pump includes a cylinder defining a chamber therein. A piston rod includes a handle mounted to a first end thereof and a piston mounted to a second end thereof, the piston being slidably received in the chamber of the cylinder. An adaptor includes a first end and a second end that is communicated with the first end. The first end of the adaptor is communicated with the chamber of the cylinder. A pressure gauge includes a tubular plug formed thereon. The second end of the adaptor is mounted around the tubular plug such that air in the chamber of the cylinder is flowable to the pressure gauge via the second end of the adaptor. A hose includes a first end for inflation and a second end for sealingly receiving the tubular plug of the pressure gauge such that air in the chamber of the cylinder is flowable to the first end of the hose for inflation.
