3/4 PVC COUPLER T X T WHITE

🧾 What it is:

A galvanized bell reducer that transitions duct size:

• 6-inch duct → 5-inch duct
• Used in HVAC airflow systems

🔧 What it’s used for:

• Reducing duct size in HVAC runs
• Connecting mismatched round duct sizes
• Air distribution systems (residential or light commercial)
• Furnace, bath fan, and ventilation ducting

⚙️ Key features:

• Galvanized steel construction (rust resistant)
• “Bell” shape for smooth airflow transition
• Slip-fit duct connection style
• Used in low-pressure air systems
• Typically part of sheet metal ductwork inventory

🧠 Simple explanation:

It’s basically a metal funnel fitting that reduces a 6-inch round air duct down to 5 inches so different duct sizes can connect together.
