<p>A pressure gauge for a foot pump comprises a housing having a connector portion on an exterior wall thereof which is formed integrally with the housing in a one-piece construction. The connector portion of the one-piece construction includes coupling members formed integrally therewith for connection to a foot pump and to a hose, and includes interior bores which define a chamber for a ball check valve and which also communicate the interior of the connector portion with the interior of the housing. The pressure gauge is preferably of the Bourdon-tube type and includes a spring tube which is pressed into a bore that extends from the interior of the connector portion through an adjacent end wall of the housing portion of the one-piece construction.</p> |
