It threads directly into exhaust ports on valves, cylinders, and manifolds to attenuate discharge noise to 84 dB while allowing up to 370 CFM of airflow. The body is constructed from polyethylene, keeping weight low and providing adequate resistance to most ambient shop environments. Overall length is 131 millimeters and outer diameter is 38.5 millimeters. Licensed HVAC, pneumatic, and industrial maintenance technicians install this type of component as part of routine valve and actuator service.\u003c\/p\u003e\u003cp\u003eThis muffler is suited for use on pneumatic control valves, directional control valves, cylinders, and solenoid valve exhaust ports that use a 3\/4 inch BSPP threaded connection. It is appropriate for both light industrial and commercial compressed air systems operating within a temperature range of -14 degrees F to 175 degrees F. Typical applications include machine control panels, automated assembly equipment, and process control pneumatics where exhaust noise at the valve stack must be managed to meet shop floor noise requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e84 dB rated exhaust noise attenuation at the valve or cylinder exhaust port\u003c\/li\u003e\n\u003cli\u003e370 CFM flow capacity supports high-cycle pneumatic valve applications\u003c\/li\u003e\n\u003cli\u003e3\/4 inch BSPP thread for direct port installation without adapters on compatible valves\u003c\/li\u003e\n\u003cli\u003ePolyethylene construction resists corrosion and keeps component weight minimal\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -14 degrees F to 175 degrees F covers most indoor industrial environments\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 131 millimeters long and 38.5 millimeters diameter for use in tight valve enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-thread exhaust muffler for pneumatic valves and actuators equipped with a 3\/4 inch BSPP exhaust port.

Hand-thread the muffler into the exhaust port first to confirm thread engagement before applying a wrench, as BSPP is a parallel thread that relies on a sealing face or thread sealant rather than taper for a pressure-tight fit. Do not overtighten into plastic or aluminum valve bodies. Installation is typically performed by industrial maintenance technicians or pneumatic system mechanics familiar with compressed air distribution and valve service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: BSPP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 370 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 84 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 131 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 38.5 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyethylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 175 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -14 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0025 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: LEGRIS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0674 00 27\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGRIS","offers":[{"title":"Default Title","offer_id":51731772375346,"sku":"0674 00 27","price":95.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e343c51a65b32b9a42fa06cb644371db.jpg?v=1788734778","url":"https:\/\/voomisupply.com\/products\/legris-0674-00-27-pneumatic-muffler-370-cfm-3-4-bspp","provider":"Voomi Supply","version":"1.0","type":"link"}
