What is a Duct Hose?


At its core definition, a ducting hose is tube-like piece of equipment, with an opening at each end, which is made to transfer something from point A to point B. But this is a broad and over-simplistic term which does not properly explain the features and functionality of Rubber-Cal’s ducting hoses. These ducts are made specifically to move a range of materials. This range includes five categories – air of varying temperatures, dust and other fine particles, abrasives, larger non-abrasive materials, and fumes.

There is no one ducting hose product which will be perfectly suited to each different type of material movement. A wide variety of hoses are available, all with different designs and made with different materials, and all boasting different capabilities. Hose materials include PVC, coated polyester fabric, neoprene, silicone, thermoplastic rubber, aluminum, stainless steel and more. Each will provide different qualities. For instance, PVC ducting can provide a high degree of flexibility, while stainless steel is ultra strong and rigid. Some materials provide a higher working temperature, while others handle exposure to chemicals. To ascertain what kind of duct is needed in any particular setting, you need to know what will be travelling through it, what temperature it must be able to handle, whether it needs any resistance to chemical exposure, whether it will be used with positive or negative pressure, and what size is needed in terms of length and diameter.

In most cases, the open ends of the ducting hose are attached in place using a connector, clamp or belt. The applications for a hose can include everything from transferring air within an air conditioning system, sucking up sand, pebbles and other small debris and abrasives, to ventilating harmful fumes. In each of these applications – and many more – the hose itself does not have any powers of positive or negative pressure. It is simply there as a conduit, providing the channel to transfer a material from A to B.

Applications for a Rubber Hose


Flexible ducting comes in a wide variety of materials and sizes, guaranteeing an ideal hose for each and every application. While it is nice to have so many options, selecting a flexible ducting made from the wrong material result in damage or total destruction of the hose. When compared to other ducting materials, the rubber hose is the most versatile option available, and luckily it comes in a variety of different elastomers and sizes to ensure a match for any application.

Unlike other ducting materials, a rubber hose can be used to transport a variety of different substances. From liquids to air, dust, and even small materials such as rocks and leaves, nearly anything can be transported through flexible rubber ducting. You will see them commonly used everywhere from a home ducting system to vacuum cleaners, motor vehicles, and industrial machinery.

Rubber flex hoses made from thermoplastic are particularly a popular choice for most applications due to their enhanced physical durability. A thermoplastic rubber hose can even be used for external applications, as the material resists ozone and UV rays better than alternatives. Thermoplastic rubber ducting can even withstand chemical exposure and high temperatures without compromising its strength or flexibility. Though other ducting materials demonstrate stronger chemical and temperature resistances, no other material offers the same wide range of physical resistances that are found in the rubber hose. For versatility and exceptional strength across the board, flexible rubber ducting is as good as it can get.

Qualities of a Great Heating Duct


Ducting comes in a wide variety of materials and sizes, guaranteeing an ideal hose for each and every application. While it is nice to have so many options, the choices can be overwhelming to a duct heating novice. It is important to choose the right heating duct for your system, otherwise you may end up with poor air quality, circulation, or worse – a damaged heater hose. Next time you are shopping for a heating air duct, make sure the product you choose hits these important points:

  1. Heat-Resistant Hose – This may seem like a no-brainer, but it is important to choose a heating duct that can handle the temperatures present in your application. There are several different kinds of heat-resistant Hose that perform under different maximum temperatures. Neoprene-coated fiberglass is a cost-effective heating duct that can handle temperatures up to 300°F, which is great for residential ducting systems. For commercial and industrial applications that experience higher temperatures, fiberglass heating hoses can be coated with silicone or aluminum.

  2. Durability – Flexible heat ducting is usually fairly sensitive, no matter what material it is made of. The risk of tears and punctures in the material is high for both transporting the heat duct and installing it. Many heating ducts come equipped with wear strips to prevent such damage and ensure safe handling of the tubing.

  3. Insulation – Regardless of whether you are installing a cooling or heating duct, insulation is an important quality to have. An insulated heating duct has an extra layer to it that protects the airflow and temperature from escaping while maintaining an efficient level of flexibility. This is important for any heat ducting system in order to ensure that air quality and temperature levels are up to par.
