WARNING: Cancer and Reproductive Harm - The “Smooth-Tube TPR” flexible hoses are medium weight hose products that are great for use in fume, light materials, dust and air movement applications. Each black rubber hose is made of thermoplastic rubber and has been reinforced with an exterior rigid polypropylene helix. A unique feature of this thermoplastic hose is its completely smooth interior. When hose and ducting materials have a smooth even interior, they greatly reduce the chances of clogs from occurring. The smooth interior helps to maximize airflow for efficient suction.
These flexible hoses are best put to use in any applications and is a general purpose hose. It has a moderate level of durability against abrasive (i.e., wood) dust particles, making it a safe choice for any applications that involve dust. Dust particles will not get stuck inside the hose thanks to the smooth interior. It is also very well suited for use in fume related jobs. Part of this strength comes from the ability of this thermoplastic hose to operate in the presence of higher temperatures and even some chemicals. In terms of its temperature range, this black rubber hose is able to operate in temperatures ranging from -60° F to 275° F.
A very important feature to have in most ducting materials is flexibility and durability. Sometimes one or the other will do, but these flexible hoses combine both! In terms of flexibility, this hose is excellent. It can be bent and flexed with ease so that you can maneuver it into position wherever it is needed. Additionally, this hose is also very durable. The key behind its physical durability is the rigid polypropylene helix that is found along its outer body. This outer helix of the black rubber hose acts as an external wearstrip that serves to enhance the protection provided to this thermoplastic hose. The outer helix protects the hose against any external abrasion. An operator can drag this hose along a rough surface without worrying about it being damaged. As an added bonus, this flexible ducting is available in a flame retardant version.
These flexible hoses are available in a variety of sizes. They come in standard lengths of 25 feet. Their available ID sizes are 2.5, 3, 4, 5, 6, 7, 8, and 10 inches. Although these flex hoses come with plain ends, you can request cuffs for them in order to facilitate a faster and easier installation.
