If you want a good aluminum flexible duct or a dependable PVC flexible hose, we have you covered! July is supposed to be a fun time for everyone, so check out what we have in order to make your life more fun and easy.
Aluminum Flex 400 Hi-Temp Hose: Made of aluminum, these flexible air ducts are built to operate in conditions that see high temperatures. This aluminum flexible duct has a working temperature range of between -100° F and 400° F. Whether the job is super cold or super hot, this metallic hose is sturdy enough to get things done. These also come with hose connectors so that they install easily without any trouble.
PVC Flexduct Light-Duty Clear Hose: Lightweight and see-through, this PVC flexible hose uses a spring steel wire helix within its body to give it a sturdy frame and allows for better compressibility. Since it is made using PVC material, this flexible hose is good at resisting the damaging effects of chemicals and moisture. This material makes it ideal for transferring away chemical fumes. It has a working temperature range that goes from -20° F to 160° F, making it better suited to lighter-duty applications.
Silico-Fiberglass 550 Flex Duct: These flexible air ducts are lightweight and red in color. Thanks to the silicone material that makes them, they are highly resistant to extreme temperatures. They can operate well within temperatures from -65° F on the low end and up to 550° F on the higher end. In fact, this hose takes its name from the highest temperature point that this ducting can operate in. As an added bonus, this flexible hose is a vivid red in color.
Ducting Basics: Hose vs Ducting
In the context of our product line, the words “ducting” and “hose” are often used interchangeably, but you should be aware that there are clear differences between the two. According to the standard definition, ducting is a system of pipes and tubes used for transferring a specific type of material, or media, from one location to another. The exact type of material can vary from air and chemical fumes to solid materials such as gravel and leaves. Keep in mind that in current industrial nomenclature, the term “ducting” is specifically meant for use with fumes and materials while “hose” is meant for the type of pipes that handle liquid. The two terms do get mixed together on occasion. It is rare to see ducting used in reference to liquid handling, but hose is often used to refer to applications that involve air and materials.
ID size is one of the key differentiating factors between hoses and ducting. ID stands for inside diameter and you can measure a duct’s ID by measuring from one end of the inside section of the wall to another. Hoses tend to be smaller in ID compared to ducts. Liquids do require higher degrees of pressure in order to be moved and smaller diameters help create the necessary pressure. Ducts, on the other hand, are found in much larger diameters because they need relatively lesser pressure in order to transfer air and materials. Some ducting is available in ID sizes that go up to 60”!
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
