With a 1\/2 inch male NPT thread and a rated flow capacity of 60 CFM, this muffler installs at the exhaust port of pneumatic valves, cylinders, and actuators to control actuator speed while dampening exhaust noise. The overall length is 2 inches and the hex size is 0.875 inches across flats. Constructed entirely from brass, it handles operating temperatures from 35 degrees F to 300 degrees F. Maintenance technicians and pneumatic systems installers fit this component during machine assembly or routine service on air-powered equipment.\u003c\/p\u003e\u003cp\u003eThis speed control muffler is suited for industrial and light commercial pneumatic systems where exhaust flow metering and noise reduction are required at valve or actuator exhaust ports. Typical applications include pneumatic directional control valves, air cylinders, and solenoid valve banks in automated equipment, assembly lines, and process control systems. The 1\/2 inch male NPT connection fits standard NPT-threaded exhaust ports common across a wide range of pneumatic components. Its compact 2 inch length allows installation in tight panel or manifold environments without interference.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2 inch male NPT thread for direct installation into standard NPT exhaust ports\u003c\/li\u003e\n\u003cli\u003e60 CFM rated flow capacity for effective speed control on mid-range pneumatic actuators\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance and durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 35 degrees F to 300 degrees F\u003c\/li\u003e\n\u003cli\u003eCompact 2 inch overall length fits restricted mounting locations\u003c\/li\u003e\n\u003cli\u003e0.875 inch hex size for standard wrench installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation speed control muffler for pneumatic valves, cylinders, and actuators with 1\/2 inch NPT exhaust ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pneumatic systems technician or maintenance mechanic. Depressurize and lock out the compressed air supply to the circuit before removing or installing any pneumatic components. Use an appropriately sized open-end or box wrench on the 0.875 inch hex to thread the muffler hand-tight and then wrench-snug into the exhaust port — do not overtighten brass fittings. Apply thread sealant compatible with compressed air systems if required by local maintenance standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMuffler Type\u003c\/strong\u003e: Speed Control Muffler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Capacity\u003c\/strong\u003e: 60 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width \/ Diameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 300 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 35 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4420001250PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51753378349362,"sku":"4420001250PRO","price":34.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e09743a9f5e2de34072fc253f422fe25.jpg?v=1788936006","url":"https:\/\/voomisupply.com\/products\/pro-source-4420001250pro-speed-control-muffler-60-cfm","provider":"Voomi Supply","version":"1.0","type":"link"}
