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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch male NPT thread for direct installation into standard exhaust ports\u003c\/li\u003e\n\u003cli\u003e20 CFM flow rating supports light-duty to medium-duty pneumatic circuits\u003c\/li\u003e\n\u003cli\u003eAluminum construction resists corrosion and keeps weight low at 0.1 pounds\u003c\/li\u003e\n\u003cli\u003eCompact 1-7\/8 inch overall length fits tight valve banks and manifold configurations\u003c\/li\u003e\n\u003cli\u003eOperating range of 35 degrees F to 160 degrees F suits most indoor compressed air environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or add-on muffler for pneumatic valves, cylinders, and solenoid valve exhausts equipped with 1\/8 inch NPT exhaust ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 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 Rating\u003c\/strong\u003e: 20 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: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.625 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\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: 4420001860PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51746183676210,"sku":"4420001860PRO","price":17.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5802bd55c0c48cbd6f17ddf13cfd778d.jpg?v=1788866859","url":"https:\/\/voomisupply.com\/products\/pro-source-4420001860pro-pneumatic-muffler-1-8-in-npt-20-cfm","provider":"Voomi Supply","version":"1.0","type":"link"}
