Pro-source 4410003850PRO Pneumatic Exhaust Muffler 3/8 in Npt

Product Description

The PRO-SOURCE 4410003850PRO is a sintered bronze pneumatic exhaust muffler designed to reduce exhaust noise on compressed air systems. Threaded with a 3/8 inch male NPT connection, it installs directly into the exhaust port of pneumatic valves, cylinders, or actuators to attenuate discharge noise to 81 dB. The sintered bronze body allows airflow while filtering particulates from the exhaust stream. At 1.5 inches overall length and 0.6875 inches overall width, it is compact enough for tight panel or manifold installations. Pneumatic technicians and maintenance mechanics install this part as a standard service item on industrial and commercial air-powered equipment.

This muffler is suited for use in industrial pneumatic control systems, automated assembly equipment, and general compressed air circuits where exhaust noise reduction is required. It fits standard 3/8 inch NPT exhaust ports on directional control valves, solenoid valves, and similar pneumatic components. The rated temperature range of 35 degrees F to 300 degrees F makes it appropriate for both ambient indoor installations and moderately elevated-temperature environments common in manufacturing and process facilities.

Key Features

• Sintered bronze construction provides durable, corrosion-resistant exhaust noise attenuation
• 81 dB decibel rating reduces pneumatic exhaust noise at the discharge port
• 3/8 inch male NPT thread fits standard pneumatic valve exhaust ports directly
• Compact size — 1.5 inches overall length, 0.6875 inches overall width — suits tight installations
• Operating temperature range of 35 degrees F to 300 degrees F for broad application compatibility
• Sintered media also acts as a particulate filter on the exhaust air stream

Compatibility

Designed as a direct-install exhaust muffler for any pneumatic valve, actuator, or cylinder equipped with a standard 3/8 inch female NPT exhaust port.

Installation Notes

Installation is performed by pneumatic technicians or qualified maintenance personnel. Depressurize and lock out the compressed air supply before servicing any pneumatic component. Thread the muffler hand-tight into the exhaust port, then snug with a wrench sized to the 0.6875 inch hex — do not overtighten sintered bronze fittings as the body can crack under excessive torque. Inspect the sintered element periodically and replace if flow restriction or visible fouling is evident.
