Threaded with a 1\/2 inch BSPP connection, it attenuates exhaust noise to a rated 108 dB level while allowing controlled airflow discharge. The stainless steel construction handles operating temperatures from -4 degrees F to 355 degrees F, making it suitable for demanding industrial environments. It is installed by pneumatic system technicians and maintenance mechanics on compressed-air circuits where port exhaust noise must be managed.\u003c\/p\u003e\n\u003cp\u003eThis muffler fits standard 1\/2 inch BSPP exhaust ports found on pneumatic solenoid valves, manifold stations, and directional control valves in industrial, manufacturing, and automation applications. Its compact overall length of approximately 0.87 inches (22 mm) allows installation in tight panel or manifold configurations where clearance is limited. The 27 mm hex size accommodates a standard open-end or combination wrench for straightforward installation and removal during routine maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch BSPP thread for direct fitment to standard metric-thread pneumatic exhaust ports\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in industrial and washdown-adjacent environments\u003c\/li\u003e\n  \u003cli\u003eRated noise level of 108 dB to characterize exhaust attenuation performance\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -4 degrees F to 355 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact 22 mm overall length suitable for space-constrained manifold installations\u003c\/li\u003e\n  \u003cli\u003e27 mm hex drive for easy installation and removal with common hand tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or new-installation exhaust muffler for pneumatic valves and actuators equipped with 1\/2 inch BSPP exhaust port threads.

Depressurize and isolate the compressed-air circuit completely before removing any existing muffler or fitting. Thread the muffler hand-tight first, then snug with a wrench on the 27 mm hex — do not overtighten, as stainless steel threads can gall. Verify the exhaust port is free of contamination before installation to prevent clogging the sintered or porous muffler element.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuffler Type\u003c\/strong\u003e: Exhaust 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: BSPP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 108 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 22 mm (approximately 0.87 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 27 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 355 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -4 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0837 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: LEGRIS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0682 00 21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGRIS","offers":[{"title":"Default Title","offer_id":51736932286770,"sku":"0682 00 21","price":111.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bd3eddfaff27cb14b8082796f8835ed.jpg?v=1788782074","url":"https:\/\/voomisupply.com\/products\/legris-0682-00-21-pneumatic-exhaust-muffler-1-2-bspp","provider":"Voomi Supply","version":"1.0","type":"link"}
