JPL MHP-25 6-in Insulated 25-ft. Flex Duct

The JPL MHP-25 6-inch x 25 feet Insulated Flex Duct is a top choice for quality HVAC installations. Designed for efficient airflow and superior thermal performance, this flexible ductwork ensures smooth and energy-efficient operation in low to medium-pressure HVAC systems.

Key Features and Benefits of JPL MHP-25 6-inch Insulated Flex Duct

• High-Quality Construction: Features an airtight, 3/8-inch oversized inner core made from two-ply polyester surrounded by fiberglass insulation for thermal control.
• Reinforced Vapor Barrier: The durable, two-ply metalized polyester vapor barrier prevents moisture damage, ensuring a long-lasting, efficient system operation.
• UL Listed and Labeled: Designed and tested to meet strict safety and performance standards, earning it a UL-181 listing and a Class 1 label.
• GREENGUARD Gold Certified: Designed with formaldehyde-free materials, it ensures a healthier indoor environment.
• Pressure Ratings: Maximum positive pressure is 6 inches w.g. (4-12 inches) and 4 inches w.g. (14-22 inches), and maximum negative pressure is 1 inch w.g. (4-10 inches) and 1/2 inch w.g. (12-22 inches).

Multiple Insulation Rated Ducts

The JPL 6-inch flexible duct is available in two insulation-rated options for your unique application and location.

• R6 Flex Duct: Built for moderate climates or interior wall installations where the temperature difference is not extreme. Ideal for standard residential HVAC installations or for connecting flex duct to bathroom fans.
• R8 Flex Duct: Designed for greater insulation efficiency, it’s perfect for regions with more extreme temperatures, or when ducts run through unconditioned spaces where there’s a significant temperature difference between the duct and surrounding air. The higher insulation rating reduces thermal loss, and enhances energy efficiency.

Selecting the correct insulation rating depends heavily on your climate conditions and installation location; however, both ducts share JPL’s exceptional quality standards.
