The “Spiral-Lock (Aramid) 570” is a flex hose that is great for use in high temperature fume exhaust applications. It is a single-ply fiberglass fabric hose that is coated with a Para-Aramid compound. This Para-Aramid coating gives the flexible exhaust hose a better resistance to high temperatures. As a result, this flexible high temperature hose can function comfortably in conditions up to 570° F, hence it’s name. It is a unique flexible vent hose to look at because it has a green outer layer and a black inner layer. This will ensure that you can always spot the hose in case it is ever used in conjunction with other types of hoses.
One of the biggest benefits of this flex hose is its ability to withstand external physical abrasions. Its durable fiberglass and Para-Aramid body is mechanically crimped and locked around a coated steel wire helix. The material is locked around the wire helix by use of a metal strip that functions as a clip. This clip is external and therefore acts as a wearstrip. A wearstrip is a very important feature to have in any flexible vent hose because there is always the chance of the hose being subjected to physical abrasions. This may come as a result of loose solid particles like rocks colliding with the hose, or the hose being dragged along a rough and uneven surface. The external metal wearstrip allows this flexible exhaust hose to last for a much longer period of time than those hoses that lack a wearstrip.
This flex hose is very popular for use in fume exhaust applications that involve extreme temperatures. This ducting product can operate in temperatures that fall between the ranges of -40° F and 570° F. The Para-Aramid coating on the body of this flexible high temperature hose is known to be a heat-resistant compound. The hose benefits from this feature. If you have a high temperature vent or exhaust application that needs a durable and dependable flex hose, then this is the product for you.
This high temperature flexible exhaust hose is available in a standard length of 25 feet. It has plain cut ends for easy installation wherever it needs to be placed. A variety of ID sizes are available to you when selecting this flexible high temperature hose. It comes in 3, 4, 5, 6, 7, 8, 9, 10, and 12 inch ID options. If you have any further questions regarding this flex hose, please contact a ducting specialist today.
