Tips Before You Buy: 4 Factors for Identifying the Best Hose

Are you in need a ducting hose, but unsure which hose is best for you? Fret not. We are here to help.
Each of our ducting hoses is made to fulfill one or more specific functions. Here are four factors that can help you identify the best hoses for your intended purpose:

The material being transported: Some hoses are better suited for carrying certain materials than others. For instance, a urethane hose is less likely to be damaged on the inside, which may be optimal for carrying abrasive materials like wood chips or small rocks. Other hoses may be unsuitable for transporting abrasive materials, but are more suitable for transporting air or fumes.

Operating Temperatures: Some hoses handle high temperatures better than others, depending partly on the material that the hose is made of. Operating temperatures vary from hose to hose, so always check a hose's specific temperature range, as a hose should not be used outside that temperature range. Consider not just the temperature inside the hose, but also the temperature outside the hose, as well as the temperature of any equipment that the hose comes into contact with.

Chemical Resistance: Depending on the material that the hose is made of, some hoses resist certain chemicals better than others. Chemical resistances vary from hose to hose and from chemical to chemical, so always check our chemical resistance chart to ensure that a hose is compatible with a particular chemical.

Pressure: Are you sucking air out of the hose, or are you blowing air into the hose? Certain hoses are more suitable for "negative" pressure, such as in a vacuum cleaner, while other hoses are more suitable for "positive" pressure, such as in air conditioning.

Once you have identified these four factors, you can narrow down which hoses are most suitable for your intended application. Need help? Have one of our flexible ducting experts help choose the proper hose for your use.

Tips To Remember Before You Buy

What is diameter?
Diameter is a very important unit of measurement when it comes to flexible duct sizing because all duct sizes are measured according to their diameters. Flexible ducting is normally sized according to the internal (or inside) diameter, often labeled as ID. How do you measure the diameter of a round object? The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points.

Do not mistake circumference for diameter
A circle is a two dimensional shape made by drawing a curve that is the same distance all around from the center. Circles have many components including: chords, curves, diameter, radius, tangents, arcs, sectors, semi circles and central angle to name a few. It was Archimedes who developed the formula for determining the area of a circle.

The diameter of a circle is the length of the line through the center and touching two points on its edge. In the figure above, drag the orange dots around and see that the diameter never changes. The diameter is also a chord. A chord is a line that joins any two points on a circle. A diameter is a chord that runs through the center point of the circle. It is the longest possible chord of any circle.

Diameter: The center of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle.

Radius: The radius is half the diameter. Radius The radius is the distance from the center to any point on the edge.

Circumference The circumference is the distance around the edge of the circle.
Diameter = 2R
R is the radius of the circle where:
C is the circumference of the circle
π is Pi, approximately 3.142

In-Season: Hose Options for Leaf Vacuum Applications

When cleaning up leaves and other fallen debris on your lawn, you generally want to use a hose with durable walls that resist internal and external damage. Here are the three best types of hoses to use as material collection ducts:

  • Thermoplastic Hoses: Thermoplastic hoses are durable and long-lasting. They are less susceptible to damage from sunlight exposure, which makes them suitable for outdoor use. These flex ducts are available with relatively thick walls that resist internal abrasion, and are reinforced with an metal wire helix that prevents the hose from collapsing from a vacuum's negative pressure. Our "Thermoplastic Flex Medium-Duty WS" has a yellow wear-strip that also protects the hose from outside abrasion, such as when being dragged along the ground.
  • Urethane Hoses: Urethane, short for "polyurethane", is an even more durable material than thermoplastics. Urethane flex hoses are highly resistant to damage from abrasive lawn debris like leaves, twigs, dirt, and rocks. This durability allows some urethane hoses to have thinner walls for increased flexibility. Others, such as our "Urethane Flex Heavy-Duty" hose, have thicker walls for even greater protection against abrasives. Urethane hoses are also available with transparent walls, allowing you to easily check for debris stuck inside the hose. As with thermoplastic, urethane hoses often feature a metal wire helix that reinforces against a vacuum's negative air pressure.
  • Smooth Hoses: Hoses with a smooth bore are ideal as material collection ducts because debris is less likely to become trapped inside the hose corrugations. With other hoses, dirt and leaves may get caught on grooves on the interior walls, leading to clogging. Smooth walls help material to pass through the hose more easily, allowing the hose to vacuum more effectively. Smooth bore hoses are available in various hose wall materials. For instance, the "Smooth-Tube PU" has urethane hose walls for internal abrasion resistance, and an external thermoplastic helix for structure and external protection.
