GV1419 Furnace Short Increaser, 4 X 5 In., 24-Gauge Galvanized

The Imperial GV1419 furnace short increaser is a galvanized steel connector designed to bridge duct sections of different diameters, smoothing transitions between 4-inch and 5-inch ducts. This increaser boosts airflow performance in HVAC systems by reducing turbulence and pressure loss, helping your ventilation network run more efficiently and quietly. Whether you're upgrading a residential heating system, servicing commercial ventilation, or maintaining an exhaust installation, this taper increaser solves the problem of mismatched duct sizes and poor airflow alignment.

Built from heavy-duty 24-gauge galvanized steel, the Imperial GV1419 resists corrosion and stands up to demanding environments. The crimped large-diameter end creates a reinforced, leak-free seal that ensures secure attachment to duct sections, while the precision-milled taper design optimizes airflow continuity throughout your system.

Features and Benefits

• 24-Gauge Galvanized Steel: Heavy-duty material provides long-lasting durability and superior rust protection in both residential and industrial applications.
• Crimped Large End: Reinforced mouth creates a tight, secure fit that eliminates air leaks and simplifies proper alignment during installation.
• Optimized Taper Ratio: The 4-inch to 5-inch taper smoothly enlarges duct diameter to improve airflow continuity and reduce pressure loss across the connection.
• Quick Installation: Pre-crimped edges allow fast fastening with standard clamps or sheet metal screws, minimizing labor time on the job.
• Versatile Use: Works in HVAC, ventilation, and exhaust systems for homes, offices, and industrial facilities.
