The Champion P10520A Inline Check Valve is an OEM replacement part for Champion air compressors, designed to permit airflow in one direction and prevent backflow when the pump stops. This 3/4-inch inline valve is identified by the P10520A model number and is used in Champion systems as the one-way check in the discharge line. As a genuine Champion component, it helps maintain system pressure and protect downstream components by blocking reverse flow in the air lines.
