An improved pressure transducer to measure and indicate fluid pressure levels including a housing in which a piston assembly is movable in response to pressure changes, the housing being of a composite material of metal and plastic and having grooves therein, the piston having bosses formed thereon to be engaged within the grooves of the housing to prevent rotation of the piston. The transducer is also designed to facilitate grounding of an electrical contact assembly located within the housing. The external portion of the housing may be formed in a hexagonl shape to facilitate installation and removal of the unit.
