Air Flow Products PI163SL26GA Snap-lock Galvanized Pipe

Product Description

The AIR FLOW PRODUCTS PI163SL26GA is a snap-lock galvanized steel pipe section used in low-pressure sheet metal ductwork systems. Fabricated from 26-gauge galvanized steel, this round pipe section measures 16 inches in diameter and 3 feet in length. The snap-lock seam construction allows the pipe to hold its cylindrical form without welding or additional fasteners along the seam. HVAC installers use this type of pipe to build and extend supply and return air trunk lines in forced-air systems. The galvanized coating provides corrosion resistance suited to both conditioned and unconditioned space installations.

This pipe section is a standard component in residential and light commercial duct fabrication and replacement work. It is typically installed in attic, crawlspace, basement, and mechanical room runs where round galvanized ductwork is specified. The 16-inch diameter suits higher-volume airflow trunks and main distribution legs branching from air handlers or furnaces. Field cutting to length is straightforward with standard sheet metal snips or a pipe cutter.

Key Features

• 26-gauge galvanized steel construction for corrosion resistance and durability
• 16-inch diameter accommodates high-volume airflow trunk applications
• 3-foot length reduces the number of joints needed on longer straight runs
• Snap-lock seam eliminates the need for welded or riveted longitudinal seams
• Compatible with standard round duct fittings, collars, and take-off boots

Compatibility

Designed as an OEM-style replacement and new-construction component for standard round galvanized ductwork systems using 16-inch diameter pipe and fittings.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handler or furnace at the disconnect before working on any connected ductwork. Secure all joints with sheet metal screws and seal with UL-listed duct mastic or foil tape rated for the application. Do not use standard cloth-backed tape as a long-term duct sealant.
