Mueller Streamline 13102516h Flex Duct 16in X 25ft R-8.0

Product Description

The MUELLER STREAMLINE 13102516h is a 16-inch diameter, 25-foot insulated flexible duct designed for HVAC air distribution in residential and light commercial applications. It features a metalized polyester outer jacket reinforced with fiberglass scrim, a double-ply black polyester inner core, and R-8.0 formaldehyde-free insulation. The silver metalized jacket provides a durable, reflective vapor barrier that helps maintain conditioned air temperatures during transport through unconditioned spaces. UL listed construction meets standard requirements for flexible air duct installations. HVAC technicians install this product as a supply or return branch run connecting main ductwork to diffusers, registers, and grilles.

This flex duct is suited for residential forced-air HVAC systems including central air conditioning and heating applications. The 16-inch diameter and 25-foot length accommodate larger trunk-to-diffuser runs common in commercial light-duty installations and larger residential systems. It ships boxed, keeping the duct compressed and protected for jobsite storage. The R-8.0 insulation value meets or exceeds energy code minimums in most jurisdictions for ducts installed in unconditioned attics, crawlspaces, and mechanical rooms.

Key Features

• R-8.0 formaldehyde-free insulation for energy code compliance in unconditioned spaces
• Metalized polyester outer jacket reinforced with fiberglass scrim for durability and vapor control
• Double-ply black polyester inner core resists tearing and maintains airflow shape
• UL listed construction for use in standard HVAC flex duct applications
• 16-inch diameter x 25-foot length suits larger supply and return branch runs
• Boxed packaging protects duct integrity during shipping and jobsite handling

Compatibility

Designed as an OEM-style replacement and new-installation flex duct for residential and light commercial HVAC air distribution systems requiring a 16-inch diameter flexible duct with R-8.0 insulation.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with SMACNA guidelines and applicable local mechanical codes. Power down the air handling system before connecting or disconnecting duct sections. Secure both ends of the flex duct with approved metal draw bands or clamps and mastic or foil tape rated for duct use — never use standard cloth duct tape. Avoid excessive bends, compression, or kinking, as these conditions significantly reduce effective airflow and system efficiency.
