Vibrations, noises and rattles resulting from operation of the fan or blower are transmitted into the metal ducts which carry the noises throughout the system. In order to isolate the vibration and noises to the source, an air-tight flexible joint, consisting of a fabric which is attached to sheet metal on both sides, must be inserted between the equipment and the ductwork. This vibration isolator is called a flexible duct connector.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWater-resistant\u003c\/li\u003e\n\u003cli\u003eFlame-resistant\u003c\/li\u003e\n\u003cli\u003eResistant to low temperature\u003c\/li\u003e\n\u003cli\u003eUpper limit continuous use (200 deg F)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eFabric\u003c\/td\u003e\n\u003ctd\u003eTechnoprene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdditional Information\u003c\/td\u003e\n\u003ctd\u003e22 oz Weight Capacity, 4 in Connection Size, 345 to 445 lb Breaking Strength\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTear Strength\u003c\/td\u003e\n\u003ctd\u003e20 to 25 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eGrip Loc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eGalvanized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMFRN Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Rating\u003c\/td\u003e\n\u003ctd\u003e-40 to 200 deg F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Duro Dyne®","offers":[{"title":"Default Title","offer_id":67952091595066,"sku":"DURMFRN444","price":497.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0569\/5238\/9827\/files\/Duro_Dyne_JFF_321d0c0f-bcab-42bc-bb3e-a41c0da81bf0.jpg?v=1794259240","url":"https:\/\/nwfsupply.com\/products\/durmfrn444","provider":"NWF Supply","version":"1.0","type":"link"}
