AUTOMOTIVE HOSE

METAL FLEX-HAND BENDABLE DUCT

Application

Used for most installation where there is no flexing, such as vent hoods, air ducts, hot air dryers. Meet UL 181 Class I air duct specification. ULCSIIO standard methods of tests for air ducts.

Construction

Aluminum interlocked construction is self supporting and hand bendable for ease of installation.
Advantages include low pressure loss and vibration dampening. Not designed to flex in service.

Working pressures are calculated at 70 degrees F (20 degrees C). Maximum working pressure decreases as temperature increases. Pressure ratings can only be achieved using proper coupling procedures. Bend radius is calculated at 70 degrees F (20 degrees C). Flexibility may vary at different temperatures. Please contact IRP if you have concerns regarding your application.
