Pro-source 4420001260PRO Pneumatic Muffler 60 Cfm 1/2 in Npt

Product Description

The PRO-SOURCE 4420001260PRO is a pneumatic exhaust muffler designed to reduce noise at air exhaust ports in compressed-air systems. Constructed from aluminum, it threads directly onto 1/2 inch Male NPT exhaust ports and allows up to 60 CFM of airflow while dampening discharge noise. At 3.25 inches in overall length and 0.875 inches in overall width, it is a compact inline muffler suited for valves, cylinders, and other pneumatic components. Licensed industrial maintenance technicians and pneumatic system installers typically specify this type of muffler where noise reduction and free exhaust flow are both required.

This muffler is used on pneumatic directional control valves, solenoid valves, air cylinders, and similar components that exhaust compressed air directly to atmosphere. It is appropriate for industrial, commercial, and light-manufacturing pneumatic circuits operating within a temperature range of 35 degrees F to 160 degrees F. The 1/2 inch Male NPT thread makes it a direct fit for standard NPT-ported exhaust outlets common across a wide range of pneumatic equipment.

Compatibility

Designed as a standard replacement or new-installation muffler for pneumatic valves and cylinders with 1/2 inch Male NPT exhaust ports.

Installation Notes

Installation and removal should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the pneumatic circuit completely before removing or installing any exhaust components. Apply thread sealant appropriate for compressed-air service and tighten using the 1.0 inch hex with a standard open-end or adjustable wrench — do not overtighten aluminum-threaded fittings. Verify the system is fully repressurized and leak-free before returning equipment to service.
