The Complete Handbook of Leaf Blower Tubes

Chapter 1: Understanding Leaf Blower Tubes

A leaf blower tube is the duct that connects the blower's impeller housing to the exit nozzle. In its most basic form, it is a simple pipe, but the geometry of that pipe determines how much air you actually deliver to the ground, how much noise reaches your ears, and how much strain you feel in your arms after an hour of work. A cheap, poorly designed tube can wipe out 30 percent of a blower's airflow, turning a 90-mph machine into a 60-mph one. This chapter explains what a leaf blower tube actually is, how the air moves through it, and why this seemingly minor accessory deserves your attention.

What A Leaf Blower Tube Is Made Of and How It Is Built

Manufacturers produce tubes in a handful of plastics, with the most common being polypropylene, ABS (acrylonitrile butadiene styrene), and, less frequently, nylon. Polypropylene is the budget material found on most residential blowers. It is lightweight and cheap to mold, but it becomes brittle at outdoor winter temperatures, and it has a low fatigue threshold, meaning it will crack after repeated bending or impact. ABS is the step up. It has greater impact resistance and a slightly heavier feel. Commercial-grade equipment often uses ABS or a rubberized polymer blend, specifically designed to survive being thrown into the back of a pickup truck. Nylon tubes, or tubes with a nylon webbing reinforcement, are the premium option, common on backpack blowers and industrial units
