It threads directly into pneumatic valves, cylinders, and actuators via a 3\/4 inch Male NPT connection and supports up to 70 CFM of airflow. The muffler measures 4.625 inches in overall length and 1.0625 inches in overall width and diameter, making it a compact fit for tight panel or manifold installations. Rated for temperatures between 35 degrees F and 160 degrees F, it suits a wide range of industrial and light commercial pneumatic applications. Aluminum construction keeps weight low at 0.1 pounds while providing corrosion resistance in typical shop-air environments.\u003c\/p\u003e\n\u003cp\u003eThis muffler is used wherever compressed air is exhausted to atmosphere and noise control is required — including directional control valves, solenoid valves, pneumatic cylinders, and filter-regulator-lubricator assemblies. It is commonly installed in manufacturing lines, automated equipment, and maintenance shops by industrial mechanics, pipefitters, or HVAC and pneumatic system technicians. The 3\/4 inch NPT thread size covers a broad range of mid-sized valve and actuator exhaust ports encountered in general-purpose pneumatic circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch Male NPT thread for direct installation into standard exhaust ports\u003c\/li\u003e\n  \u003cli\u003e70 CFM airflow capacity handles mid- to high-volume exhaust applications\u003c\/li\u003e\n  \u003cli\u003eAluminum body provides corrosion resistance with minimal weight at 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 35 degrees F to 160 degrees F suits most indoor pneumatic environments\u003c\/li\u003e\n  \u003cli\u003eCompact 4.625 inch overall length fits tight installations on valve banks and manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-thread replacement muffler for pneumatic valves, cylinders, and actuators with 3\/4 inch Male NPT exhaust ports in general-purpose compressed air systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by industrial mechanics, pipefitters, or qualified pneumatic system technicians. Depressurize and isolate the pneumatic circuit completely before removing the existing muffler or installing this unit. Use a wrench on the 1.625 inch hex to thread the muffler hand-tight first, then snug with a wrench — do not overtighten aluminum-threaded fittings into ported valve bodies. Verify there are no air leaks at the NPT joint before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuffler Type\u003c\/strong\u003e: Muffler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 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 Rate\u003c\/strong\u003e: 70 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 160 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4420003460PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51748523245874,"sku":"4420003460PRO","price":40.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3d712c1b483e90582c15ddd2931af05.jpg?v=1788894772","url":"https:\/\/voomisupply.com\/products\/pro-source-4420003460pro-pneumatic-muffler-70-cfm-3-4-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
