Product manifolds for use with portable oxygen concentrators and portable oxygen concentrators including such product manifolds. An example product manifold for use with a portable oxygen concentrator includes a body, a first product port, a second product port, an accumulator port, an output port, and a flow path. The flow path fluidly couples the first product port, the second product port, the accumulator port, and the output port. The product manifold includes a first control port, a second control port, and a third control port. The first, second, and third control ports fluidly couple the flow path. The product manifold also includes a first solenoid valve assembly, a second solenoid valve assembly, and a third solenoid valve assembly. The first, second, and third solenoid valve assemblies are secured to the body of the product manifold adjacent the first, second, and third control ports, respectively, by a corresponding snap fit connector.

Product manifolds for use with portable oxygen concentrators and portable oxygen concentrators including such product manifolds. A product manifold for use with a portable oxygen concentrator includes a first product port, a second product port, an accumulator port, an output port, and a flow path. The flow path operatively coupling each of the first product port, the second product port, the accumulator port, and the output port to one another. The product manifold includes a plurality of control ports. Each of the control ports fluidly coupling the flow path. The product manifold includes a first orifice disposed in a first portion of the flow path; a second orifice disposed in a second portion of the flow path; and a third orifice disposed in a third portion of the flow path. Each of the first orifice, the second orifice, and the third orifice being formed by an electrical forming process and having a thickness of between about 0.0025 inches and about 0.004 inches.
