Duro Dyne jbx100 Flexible Duct Connector Ul R4462

Product Description

The DURO DYNE jbx100 is a black flexible duct connector designed for HVAC air distribution systems where vibration isolation between equipment and ductwork is required. Built from a nylon and polyester fabric blend with a vinyl coating, this junior Excelon connector resists water, mildew, and tearing under normal service conditions. It carries UL R4462 recognition, confirming it meets established safety standards for flexible duct connectors. Licensed HVAC technicians and sheet metal contractors install this type of connector to prevent fan and air handler vibration from transmitting into the duct system and occupied spaces.

The jbx100 is suited for residential and light commercial HVAC installations where a compact, all-purpose flexible connector is needed at supply or return air openings, fan inlets, or air handler connections. Its black finish and junior sizing make it appropriate for applications with tighter clearances or where aesthetics at exposed connections matter. The UL R4462 listing supports its use in systems requiring code-compliant flexible duct connector materials.

Key Features

• Nylon and polyester fabric construction with vinyl coating for durability
• Resistant to water, mildew, and tearing for long service life
• UL R4462 recognized for code-compliant installations
• Black finish suitable for exposed or semi-exposed applications

Compatibility

Designed as an OEM-style flexible duct connector for residential and light commercial HVAC systems requiring a UL-recognized, fabric-based vibration isolation connector at fan, air handler, or ductwork transitions.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal contractor in accordance with local mechanical codes and the equipment manufacturer's guidelines. Disconnect and lock out power to the air handling unit or fan before beginning connector installation. The connector should be installed without excessive tension or compression so it can perform its intended vibration isolation function. Avoid contact with sharp edges that could cut or abrade the fabric material over time.
