The bellows assembly accommodates thermal expansion and pressure fluctuations inherent to steam systems, allowing controlled movement that reduces mechanical stress on connected components. By flexing with system changes, it helps protect boiler piping and fittings from fatigue caused by repeated expansion and contraction cycles. Licensed HVAC technicians and steam heating specialists typically install this assembly as part of routine system maintenance or component replacement. The unit weighs 1.43 pounds and is also referenced by the designation SA47-104.\u003c\/p\u003e\u003cp\u003eThis assembly is suited for steam boiler and heating system installations where thermal movement and pressure variation must be managed at connection points. It is typically found in hot-water or steam distribution piping assemblies where flexibility is required to maintain long-term system integrity. Steam heating applications in both light commercial and residential boiler systems represent its primary install environment. Installers working on older steam distribution networks will find this a direct-fit replacement for worn or failed bellows components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLarge bellows construction accommodates thermal expansion and contraction in steam systems\u003c\/li\u003e\n\u003cli\u003eActs as a protective mechanism against pressure-induced stress on piping and system components\u003c\/li\u003e\n\u003cli\u003eReferenced under designation SA47-104 for cross-reference identification\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 1.43 pounds for straightforward handling during installation\u003c\/li\u003e\n\u003cli\u003eOEM part number 341900 ensures direct replacement fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement bellows assembly for steam heating and boiler systems where a large bellows component is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or steam systems specialist familiar with low-pressure steam boiler service. Shut down the boiler and allow the system to fully depressurize and cool before removing or installing any bellows assembly. Inspect surrounding piping and fittings for wear or corrosion during the service call. Follow applicable mechanical codes and the boiler manufacturer guidelines for proper component orientation and connection integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.43 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number\u003c\/strong\u003e: 341900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Designation\u003c\/strong\u003e: SA47-104\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: XYLEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 341900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XYLEM","offers":[{"title":"Default Title","offer_id":51468235866418,"sku":"341900","price":586.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945983.jpg?v=1783915390","url":"https:\/\/voomisupply.com\/products\/xylem-341900-large-bellows-assembly-steam-heating","provider":"Voomi Supply","version":"1.0","type":"link"}
