Constructed from bronze with a 40-micron filtration rating, it vents pressurized air while filtering particulates from re-entering the system. The compact body measures 5\/8 inches in overall length and 9\/16 inches in overall width, making it suitable for tight panel or manifold installations. Rated for temperatures from 35 degrees F to 300 degrees F, it handles the thermal range typical of industrial and commercial pneumatic systems. Pneumatic technicians and maintenance mechanics install this fitting as a standard exhaust port silencer.\u003c\/p\u003e\n\u003cp\u003eThis muffler fits standard 1\/4 inch NPT exhaust ports found on pneumatic solenoid valves, air cylinders, and valve manifolds in industrial automation, HVAC controls, and fluid-handling equipment. It is suited for both stationary and mobile pneumatic circuits where exhaust noise reduction and particulate exclusion are required. The bronze construction resists corrosion in environments where moisture or mild chemicals may be present at the exhaust port.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-micron filtration rating controls particulate ingestion through the exhaust port\u003c\/li\u003e\n  \u003cli\u003eBronze construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch male NPT thread fits standard pneumatic valve exhaust ports\u003c\/li\u003e\n  \u003cli\u003eCompact body: 5\/8 inches overall length, 9\/16 inches overall width\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: 35 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch hex size allows installation and removal with a standard wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new installation muffler for any pneumatic valve, cylinder, or manifold with a 1\/4 inch female NPT exhaust port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and lock out the pneumatic circuit before removing or installing any exhaust port fittings. Thread the muffler hand-tight into the valve exhaust port, then snug with a wrench to the 9\/16 inch hex — do not overtighten bronze fittings, as the material is softer than steel and susceptible to thread damage. Apply thread sealant only if required by the system; many pneumatic exhaust ports do not require sealant. Verify there are no downstream back-pressure restrictions that could block the vent path after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuffler Type\u003c\/strong\u003e: Breather Vent Muffler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/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\u003eMaterial\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicron Rating\u003c\/strong\u003e: 40 microns\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 9\/16 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 25173702\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: 4430001450PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51737636143410,"sku":"4430001450PRO","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/793e7cdd64e66c919e5b1eeae178193f.jpg?v=1788791698","url":"https:\/\/voomisupply.com\/products\/pro-source-4430001450pro-breather-vent-muffler-1-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
