Pro-source 4420001860PRO Pneumatic Muffler 1/8 in Npt 20 Cfm

Product Description

The PRO-SOURCE 4420001860PRO is an aluminum pneumatic muffler designed to reduce exhaust noise on compressed air systems. It threads directly into valve exhausts, solenoid valves, cylinders, and other pneumatic components via a 1/8 inch male NPT connection. Rated for up to 20 CFM of airflow, it handles typical light-duty to medium-duty pneumatic circuits without restricting system performance. The sintered aluminum body allows air to pass through while absorbing sound energy. Overall length is 1-7/8 inches and overall width is 1/2 inches, making it compact enough for tight valve banks and manifold assemblies.

This muffler is suited for use in industrial automation, manufacturing, and maintenance applications where pneumatic valve exhaust noise must be controlled. It fits standard 1/8 inch NPT exhaust ports found on directional control valves, solenoid valves, and air cylinders in both shop and field installations. The operating temperature range of 35 degrees F to 160 degrees F covers most indoor compressed air environments. Maintenance technicians and pneumatic system installers typically source this type of muffler as a direct replacement or upgrade on existing valve assemblies.

Key Features

• 1/8 inch male NPT thread for direct installation into standard exhaust ports
• 20 CFM flow rating supports light-duty to medium-duty pneumatic circuits
• Aluminum construction resists corrosion and keeps weight low at 0.1 pounds
• Compact 1-7/8 inch overall length fits tight valve banks and manifold configurations
• Operating range of 35 degrees F to 160 degrees F suits most indoor compressed air environments

Compatibility

Designed as a standard replacement or add-on muffler for pneumatic valves, cylinders, and solenoid valve exhausts equipped with 1/8 inch NPT exhaust ports.

Installation Notes

Installation is performed by maintenance technicians and pneumatic system mechanics. Depressurize and lock out the compressed air supply before servicing any valve or cylinder. Thread the muffler hand-tight into the exhaust port, then snug with a wrench to the hex flats — do not overtighten, as aluminum threads can be damaged. Inspect the muffler periodically for clogging from oil mist or particulate, which will restrict exhaust flow and slow actuator cycling speed.
