The "Spiral-Lock (Neoprene) 250" is a high temperature duct that is made from single-ply neoprene coated polyester fabric that is mechanically crimped in a continuous process. This product is coated with Neoprene rubber and is recommended for fume ducting applications. Neoprene is a synthetic rubber (produced by the polymerization of chloroprene) and offers good chemical resistance and flexibility over a wide range of temperatures. This flex duct’s fabric is locked around a coated steel wire by a metal strip which is formed into a clip. This metal clip acts as a wear-strip that protects the integrity of the "Spiral-Lock (Neoprene) 250" and provides excellent abrasion resistance. This hose is also extremely flexible, making it ideal for hard to reach areas that require ventilation.
The "Spiral-Lock (Neoprene) 250" high temperature duct operates at both high and low temperatures. This hose has a working temperature range of -65 degrees to +250 degrees Fahrenheit. The neoprene coating allows the high-temp exhaust hose to maintain its flexibility over a broad range of temperatures while resisting degradation more than natural or synthetic rubbers. The combination of the abrasion resistance of Neoprene and the exterior metal clip makes this hose ideal for vehicle exhaust applications that may see external abrasion. If this high-temp exhaust hose requires even more external protection, a polyurethane clip cover designed to protect the helix is also available.
The "Spiral-Lock (Neoprene) 250" fume ducting comes in a standard length of 25 feet with plain cut ends and a black finish. Internal diameter sizes for this flex duct range from 3 to 18 inches. This hose is also quite compressible; larger sizes (7 inch and up) have a compression ratio of 10 to 1, which means that a 25 ft length of hose could compress down to 2.5 feet. This flexibility makes the product easy to handle in small crowded environments where maneuverability is a must. This product is great for use in fume applications such as pollution control, landfill venting, welding, and other vehicle exhaust systems.
