Mueller Industries A15631 Inline Check Valve 5/8" ODF

The Mueller Industries A15631 Inline Check Valve is a refrigerant flow control component that allows movement in one direction while preventing reverse flow within the line. It features a 5/8" ODF connection size, enabling integration into refrigerant piping sections of the system. The internal valve mechanism opens under forward pressure and closes when backflow conditions occur maintaining directional stability within the circuit. In HVAC systems such as air conditioning units, heat pumps, and refrigeration assemblies, it contributes to controlled refrigerant movement between key cycle sections. Installed inline within the refrigerant path, it supports one-way flow across connected piping sections.
