Mueller Streamline 16MD Mobile Home Flex Duct R-4.2

Product Description

The MUELLER STREAMLINE 16MD is a large-diameter flexible HVAC duct engineered for manufactured and mobile home heating and cooling systems that require higher airflow capacity. Built with R-4.2 thermal insulation and a flexible construction, this duct supports efficient routing through confined spaces typical of manufactured housing. At 16 inches in diameter, it is sized for primary trunk runs where volume, flexibility, and installation efficiency are critical. Licensed HVAC technicians working in mobile and manufactured housing will find this duct well-suited to high-demand distribution applications.

This flex duct is intended for manufactured and mobile home HVAC installations where primary trunk or large-branch duct runs are required. The 16-inch diameter makes it appropriate for main supply or return trunk applications in systems with higher airflow demands. Its flexible design allows routing around structural framing, floor joists, and other obstructions common in mobile home chassis configurations without requiring rigid duct transitions at every turn.

Key Features

• 16-inch diameter sized for primary trunk runs in manufactured housing HVAC systems
• R-4.2 insulation value helps reduce thermal loss along duct runs
• Flexible construction allows routing in confined or irregular spaces
• Supports higher airflow capacity demands in larger mobile home systems
• Designed to reduce the need for rigid duct transitions in tight installation areas

Compatibility

Designed as an OEM-style replacement or new-installation flex duct for manufactured and mobile home HVAC distribution systems requiring 16-inch flexible ducting.

Installation Notes

Installation should be performed by a qualified HVAC technician familiar with manufactured housing duct systems and applicable mechanical codes. Power the HVAC system down completely before disconnecting or connecting duct sections. Secure all connections with approved duct clamps or mastic per local code requirements, and avoid sharp bends that can restrict airflow or damage the duct liner. Follow HUD Manufactured Housing Construction and Safety Standards where applicable for mobile home duct installations.
