Air Flow Products PI145SL Snap-lock Galvanized Pipe 28GA 14in X 5ft

Product Description

The AIR FLOW PRODUCTS PI145SL is a snap-lock galvanized steel pipe section used in residential and light commercial HVAC duct systems. Fabricated from 28-gauge galvanized steel, this straight pipe section measures 14 inches in diameter and 5 feet in length. The snap-lock seam construction allows for fast field assembly without additional tooling, making it a practical choice for ductwork runs where speed and reliable joint integrity are priorities. HVAC installers and sheet metal contractors use this pipe as a core component in supply and return air distribution systems.

This pipe section is suited for low-pressure forced-air duct installations in residential and light commercial buildings. It connects to standard round duct fittings, elbows, tees, and takeoffs of matching diameter. The 14-inch diameter and 5-foot length make it appropriate for main trunk extensions or large-diameter branch runs where airflow capacity requirements are significant. Licensed HVAC technicians and sheet metal workers are the typical installing trade for this size of round duct pipe.

Key Features

• 28-gauge galvanized steel construction for corrosion resistance in conditioned air applications
• Snap-lock seam for fast, tool-free field assembly
• 14-inch diameter accommodates high-volume airflow branch and trunk runs
• 5-foot section length reduces the number of joints needed in long duct runs
• Compatible with standard round duct fittings and accessories of matching diameter

Compatibility

Designed as an OEM-style round duct pipe section for use with standard 14-inch diameter galvanized round duct fittings, collars, and accessories in forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and applicable local mechanical codes. Always de-energize and lock out the air handling system before connecting or modifying duct sections. Secure all joints with sheet metal screws and seal with code-approved duct mastic or listed duct tape to maintain system pressure integrity. Support the pipe at intervals required by local code to prevent sagging.
