Abstract
A pressure tank connector apparatus is described with a connector fitting having a fitting insert sleeve of steel or other harder metal than the fitting body which is crimped over an outwardly extending flange or lip portion of the tank wall surrounding the opening in the pressure tank to which the connector is attached to position the fitting body within the tank and spaced inwardly from the flange. The fitting body is molded of aluminum alloy and the insert sleeve is embedded into the body during molding. A plurality of spaced hemispherical projections are molded onto the outer side of the fitting body and mate with correspondingly shaped indentations on the inner side of the tank wall portion surrounding such opening to prevent rotation of the fitting when a tank connector member is threaded into the central passage of such fitting body. A sealing ring of elastomer material is clamped between the outer side of the fitting body and the inner side of the tank wall at a position surrounding the fitting insert sleeve, in order to provide a gas tight seal. As a result, the pressure tank connector apparatus is safe and strong so that it is capable of withstanding much higher pressures than atmospheric pressure, such as a working pressure of 150 psi and a failsafe pressure of five times that amount. Thus, the invention is suitable for use as a connector for an air brake tank on a truck or other vehicle.
