Lambro Industries 427 Aluminum Snap Lock Vent Pipe 4x60

Product Description

The LAMBRO INDUSTRIES 427 is a snap-lock aluminum vent pipe designed for dryer exhaust and general air-duct applications. Measuring 4 inches in diameter and 60 inches in length, this rigid aluminum pipe connects sections without tools using a snap-lock seam that resists separation under normal duct pressure. Aluminum construction keeps the pipe lightweight while providing resistance to moisture and heat typical of dryer exhaust systems. HVAC technicians and sheet metal installers use this pipe in new construction and retrofit duct runs where a rigid, low-profile connection is required.

This pipe is suited for residential and light-commercial dryer exhaust venting, as well as makeup-air and general ventilation duct runs. The 4-inch diameter matches the standard outlet size on most residential dryer units and aligns with common exhaust hood and wall-cap openings. Its 60-inch length reduces the number of joints needed in straight duct runs, minimizing potential leak points. Installers working on tight vertical or horizontal runs benefit from the rigid form factor over flexible foil alternatives.

Key Features

• Snap-lock seam construction for tool-free assembly and a secure, pressure-resistant joint
• 4-inch diameter matches standard residential dryer exhaust outlets and wall caps
• 60-inch length reduces joint count in straight duct runs
• Rigid aluminum construction resists heat, moisture, and deformation
• Sold in a package of 10 pieces per unit of measure

Compatibility

Designed as an OEM-style replacement and new-installation component for 4-inch rigid aluminum dryer exhaust and general ventilation duct systems.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal installer in accordance with local mechanical codes and the appliance manufacturer's venting requirements. Disconnect power to the dryer before disconnecting or connecting any duct sections. Secure joints with approved metal foil tape rather than screws, which can catch lint and create a fire hazard inside the duct run. Keep total duct length and elbow count within the dryer manufacturer's equivalent-length specifications.
