Vibrations, noises and rattles resulting from operation of the fan or blower are transmitted into the metal ducts which carry the noises throughout the 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 side, must be inserted between the equipment and the ductwork. This vibration isolator is called a " Flexible Duct Connector ".Excelon5R4462-40 F. to 180 2215,000 cycles350100/100240/220 Woven Nylon/Polyester BlendVinylHigh Tear StrengthHigh AbrasionResistanceMBX333 (#10159)MB6X363 (#10160)MBX444 (#10210)MSPX444 (#10264)MBX464 (#10214)Thermafab R4462-65 F.
