P/N 67389 ARO Muffler Kit
The ARO 67389 Muffler Kit is engineered for use on the valve exhaust ports of compatible heavy-duty pneumatic equipment, including larger air-operated diaphragm pumps and industrial piston pump air motors. This specialized exhaust accessory is designed to significantly reduce operational noise levels and act as an efficient air diffuser for continuous pneumatic workflows.
Inside the package, the kit supplies the essential assembly components required for a complete setup—including the designated exhaust muffler configuration and the matching 96451 elbow connection. Built with durable materials to handle high-volume exhaust discharge, these components maintain optimal airflow performance while preventing particulate debris from entering the valve system during exhaust cycles.
Proper installation involves shutting down the air supply, bleeding off all pneumatic pressure, and securely threading the components into the pump's exhaust port using appropriate thread sealant. Routine maintenance involves inspecting the exhaust path and cleaning or replacing the assembly if airflow restriction occurs, ensuring your pneumatic equipment continues to run quietly and efficiently.
