Air Flow Products PI125SL26GA Snap-lock Galvanized Pipe

Product Description

The AIR FLOW PRODUCTS PI125SL26GA is a snap-lock galvanized steel pipe section used in low-pressure residential and light commercial duct distribution systems. Manufactured from 26-gauge galvanized steel, this pipe ships as a 12-inch diameter by 5-foot length section and assembles without tools using its factory-formed snap-lock seam. The snap-lock construction allows field techs to complete straight-run duct assemblies quickly and consistently. It is a standard component in trunk-and-branch and extended plenum supply systems installed by sheet metal workers and HVAC technicians.

This pipe is suited for supply and return air duct runs in residential forced-air heating and cooling systems, as well as light commercial applications where round galvanized duct is specified. It connects to standard round duct fittings, collars, and takeoffs of matching diameter. The 5-foot section length keeps joint counts manageable on longer straight runs, reducing potential air leakage points when properly sealed.

Key Features

• 26-gauge galvanized steel construction resists corrosion in typical indoor duct environments
• 12-inch diameter suits high-volume trunk runs and main supply branches
• 5-foot section length reduces the number of joints on straight runs
• Snap-lock seam assembles without additional fasteners along the seam
• Compatible with standard round duct fittings, elbows, and takeoffs at matching diameter

Compatibility

Designed as an OEM-style round duct component for use with standard 12-inch round galvanized duct fittings, collars, and transitions in residential and light commercial forced-air systems.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers in accordance with SMACNA duct construction standards and applicable local mechanical codes. Power down the air handling unit and close the supply air damper before cutting into or extending an existing duct system. Seal all joints and seams with listed duct sealant or UL 181-listed tape per code requirements. Support horizontal pipe runs at intervals consistent with local mechanical code requirements to prevent sag and maintain system integrity.
