What is PVC Ducting?
PVC ducting, sometimes known as vinyl hose, is a very flexible and affordable hose used in the movement of material, air and dust. PVC hoses are used for many commercial applications because they are affordable, durable, offer good chemical resistance, and are available in a variety of grades. To its credit, PVC hose is perhaps one of the most versatile types of ducting on the market. Flexible PVC ducting products can be used to move air in portable A/C units, move dust in woodworking applications, convey paint fumes, or move bulk materials in agricultural applications. The combination of flexibility, durability, and chemical resistance innate to PVC hoses allows them to function remarkably in a sundry of different applications. PVC hoses are available in clear, blue, FDA grade, a thick-walled material handling version, and thin wall general purpose flex hoses. PVC ducting is not only economical, but its construction materials make it resistant to many elements to make it a great alternative to other forms of ducting.

Are PVC Hoses Chemical Resistant?
PVC hoses are resistant to corrosive materials that can be extremely destructive to most metal hoses. Chemical stability is a common feature among substances containing halogens such as chlorine and fluorine. This applies to PVC resins, which possess oil/chemical resistance. Because of this excellent chemical resistance, PVC ducting is often used in applications that involve the use of hazardous chemicals and fuels. Due to this innate resistance to damaging chemicals and fumes, PVC hoses are capable of functioning in a wide variety of situations. Whether it is as a floor duct in a laboratory, or a lightweight hose providing ventilation in an attic, PVC hoses are a superior product for virtually all situations.

How Flexible is a PVC Duct Hose?
Another beneficial characteristic of PVC hoses is that they are ultra-flexible and surpass the flexibility of other plastic products such as polyurethane and thermoplastics. This flexibility is not at the cost of flex-fatigue, rather PVC ducting is more flexible and more durable when exposed to continuous flexing than other hoses. PVC can be continuously bent and moved without causing damage or weakening the hose, making flexible PVC ducting ideal for applications that require the hose to be continuously bent and moved, like portable air conditioners. This means that you can often utilize lengths of PVC ducting to form elbows, dips, and twists in a system often without needing joints or other types of connectors.

What Available Colors are There in PVC Ducting?
Flexible PVC ducting is available in blue, clear, and translucent blue. There are benefits to using colored lengths of PVC ducting on several levels. Primarily, colored PVC ducting is used to match the aesthetic choices and different colors functionally behave the same way. However, an additional benefit is that color coded PVC hoses can be used to denote and distinguish different types of ducts from one another. Electrical ducts could be blue, whereas water outflow flex ducts could be clear, for instance. Clear, see-through types of PVC hoses are additionally popular because they allow users to observe the contents of their duct while functioning. This means that clogs, ruptures, and contaminants can readily be identified and dealt with, without needing to open up or turn off your flex ducting systems. Clear PVC ducting allows the operators to easily see any blockage that has built up in the duct, allowing for easy maintenance. Another benefit of our clear flexible PVC ducting is that these options are made of FDA approved materials to allow the flex ducts to be used in applications involving food and pharmaceutical materials.

“Tornado Flex”
What is PVC? Is PVC good for ductwork?
The first patent for a polymerisation process to manufacture PVC was granted to German inventor Friedrich Klatte in 1913 and PVC has been in commercial production since 1933. Polyvinyl Chloride material now accounts for about 25% of all plastic produced. Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. Polyvinyl Chloride is used widely in everyday applications including in manufacturing, transportation, packing, electronics and pharmaceutical applications.
PVC is a very durable and long-lasting material available in either rigid (e.g., PVC pipe) or flexible (e.g., hose). Malleable and flexible PVC products can have various additives such as protection against fire, against chemicals, FDA grades and protection against UV rays. Some end products in flexible PVC are optimal for pharmaceutical use, as the material is non-toxic, stable, and resistant, withstands temperature changes, is optimal for the sterilization process and is biocompatible in organic media.

Commonly Asked Questions About PVC Flex Ducts (Part#1)
- Can you use PVC for a range hood duct?
This is not recommended since PVC flex ducting only has a working temperature range of +160℉. Range hoods require non-flammable ducts that can handle high temperatures. Aluminum and especially stainless steel are recommended for this type of use. - Are PVC hoses safe?
PVC flex ducts are safe to be used in when moving air, dust, fumes and light materials. When flexible hoses made out of PVC are used in the operating temperatures recommended and/or checmials fumes that are compatible with their use, PVC hoses are safe. As an example, the “PVC Flexduct Light Duty Clear” is manufactured with FDA acceptable materials and is safe enough to be used in food processing facilities. Like any other class of products, as long as the hoses are used within the approved parameters set for the PVC hose, they are safe to use. - Can you cut PVC flexible ducting?
PVC flexible ducts can be cut by using a utility knife to cut through the PVC material of the hose. Once the spring steel wire is exposed, you can use a bolt cutter to cut the wire. Flexible ducting is easy to cut and to install, which is why it is widely used across many industries. - Can you use hose clamps on a flexible PVC hose?
Flexible hoses made out of PVC can be clamped down using a standard worm gear clamp (i.e., screw clamp). The material is flexible enough that when the end of the hose is exposed (i.e., the plastic), it is easy to clamp it down onto a piece of pipe. - How do you connect a PVC flexible hose to a PVC pipe?
A flexible hose can fit over a PVC pipe given that the inside diameter of the flexible hose is the same as the outside diameter of the PVC pipe. Flexible hoses are always measured by their inside diameter for the very reason that they are designed to fit over a pipe or a connector with the same outside dimension. - How do you connect PVC ducts? How do you join PVC ducts?
Adjoining PVC ducting can be connected using an aluminum or stainless connector. The two ducts will get pulled over each side of the connector and they will be clamped onto the connector. As long as the flex ducts have the same inside diameter dimension, they can be coupled by a connector that has the same outside diameter dimension. Connectors are commonly known as straight unions and are very simple way to elongate the ductwork.

Commonly Asked Questions About PVC Flex Ducts (Part#2)
- Does PVC hose stretch?
All PVC flex ducts have a PVC wall but the construction is reinforced with a spring steel wire helix. This means that the hose’s diameter cannot be stretched more than a few millimeters to fit over a larger pipe. The PVC wall itself when exposed in the ends of the hose will stretch, but the steel construction of the helix does not. - How do you attach a PVC hose?
A PVC hose is installed by pulling the hose over a pipe that is connected to the machinery like a humidifier or a swamp cooler. When the hose is pulled over the exposed section of the equipment, then it is clamped down with a screw clamp. - How do you bend PVC hose?
PVC duct hoses are extremely flexible and can be flexed easily. A four-inch diameter flex duct in a 25 foot length can be twisted into a knot perhaps 4-5 times. PVC duct hoses are among the most flexible hoses available and flexibility is the prime reason for their use. - How long do PVC hoses last?
If permanently installed indoors and the duct hoses are not continuously exposed to flexing, a PVC duct should last 15-20 years. When exposed to the elements, PVC is expected to last more than 10 years outdoors. A hose will wear from flex fatigue if it is constantly moved. In addition, if the hoses are used to move materials, abrasives or dust, the life of the hose will shorten due to interior abrasion. Life expectancy of hoses is shortened when they are exposed to elements, elevated temperatures, corrosive fumes, exterior and interior abrasion, and uninterrupted movement.
