Air Flow Products PI203SL Snap-lock Galvanized Pipe 26GA

Product Description

The AIR FLOW PRODUCTS PI203SL is a snap-lock galvanized steel pipe section used in residential and light commercial HVAC duct systems. Fabricated from 26-gauge galvanized steel, this pipe measures 20 inches in diameter and 3 feet in length, making it well suited for main trunk or branch runs where a secure, tool-minimal connection is needed. The snap-lock seam construction allows the pipe to be locked into shape on the job without additional fasteners along the longitudinal seam, saving time during installation. HVAC sheet metal installers and duct fabricators are the primary trades that work with this product.

This pipe section is used in forced-air heating and cooling distribution systems, typically as part of a round duct run connecting an air handler, furnace, or fan coil to downstream fittings, branches, or registers. The 20-inch diameter is common in larger residential systems and light commercial applications where higher airflow capacity is required. It connects to standard round duct fittings, collars, and elbows of matching diameter.

Key Features

• 26-gauge galvanized steel construction for corrosion resistance in conditioned-air applications
• Snap-lock seam design allows fast field assembly without additional seam fasteners
• 20-inch diameter accommodates high-volume airflow runs
• 3-foot length provides a manageable section for trunk and branch duct layouts
• Compatible with standard round duct fittings and collars of matching diameter

Compatibility

Designed as an OEM-style round duct pipe section for use with standard 20-inch diameter snap-lock or slip-fit galvanized duct fittings in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with SMACNA duct construction standards and applicable local mechanical codes. Power down and lock out the air handling equipment before connecting or modifying duct sections. Seams and joints should be sealed with listed duct mastic or UL 181-rated tape to maintain system air tightness. Support spacing should follow SMACNA guidelines for the pipe diameter and gauge.
