Highly flexible-Eliminates the need for elbow fittings.
Non-kinking - Permits full airflow, even with 90 deg. bends.
Self-supporting - Unique wire-reinforced polypropylene construction allows hose to maintain its shape and support itself once it is positioned. Note: Applications requiring larger IDs and longer lengths may require additional fixed supports to ensure intended performance.
Highly extendible and contractible - Hose extends easily and can be contracted to approximately one-third of its full extended working length for storage, shipping, or where the full length is not required... requires less storage space, reduces transportation costs (a 20' length can be shipped via UPS). Note: The true ID dimension of the hose can only be measured while the hose is fully extended. The true ID becomes smaller while the hose is in the contracted state.
Simple interlock connection - Joining two pieces of Extendo-Duct; is easy! Just twist the end of one hose into the end of another. No fittings, menders or couplings needed!
Light weight - a twenty-foot length of 12" diameter Extendo-Ductweighs approximately 18 Ibs. Makes difficult installations easier, reduces installation costs.
Chemically-resistant, with no off-gassing - Inert polypropylene material produces no off-gassing and is resistant to a wide variety of chemical fumes, making Extendo-Duct; ideal for clean room and chemical fume exhaust applications
Wide range of working temperatures - Extendo - Duct is suitable for use in temperatures ranging from -4 deg. F (-20 deg. C) to 175 deg. F(80 deg. C).
