Hi-tech Duravent 033801000001 Vacuum Duct Hose 1 in Id 25 Ft

Product Description

The HI-TECH DURAVENT 033801000001 is a polyurethane vacuum duct hose designed for demanding suction and transfer applications. It features a 1-inch inside diameter, a 28 Hg vacuum rating, and a 15 psi maximum working pressure, making it suitable for systems that require reliable low-pressure containment under continuous vacuum. The clear polyurethane construction allows visual flow monitoring while resisting acid, alkali, oil, and solvent exposure. With a temperature range of -40 degrees F to 250 degrees F, this hose maintains flexibility and structural integrity across a wide range of operating environments. It is typically installed by mechanical contractors and industrial service technicians.

This hose is rated for pellet transfer applications and is sold in a 25-foot length. The 7/8-inch minimum bend radius allows routing through tight equipment cabinets and duct runs without kinking. The clear finish aids in monitoring flow and detecting blockages during operation. Its resistance to multiple chemical classes makes it a practical choice for light industrial, HVAC accessory, and bulk material handling setups where standard PVC duct hose would degrade prematurely under chemical exposure or temperature cycling.

Key Features

• 1-inch inside diameter with 1-1/4 inch outside diameter for standard hose fitting compatibility
• 28 Hg vacuum rating supports high-suction transfer systems
• 15 psi maximum working pressure for low-pressure positive-flow applications
• Polyurethane construction resists acid, alkali, oil, and solvent exposure
• Wide operating range of -40 degrees F to 250 degrees F maintains flexibility in cold and hot environments
• Clear hose color enables visual flow and blockage inspection without disconnecting the line

Compatibility

Designed for pellet transfer applications and compatible with vacuum duct systems requiring a 1-inch inside diameter flexible hose with 28 Hg vacuum rating and polyurethane chemical resistance.

Installation Notes

Install using clamps or fittings rated for the system vacuum and pressure levels. Depressurize and de-energize the system fully before connecting or disconnecting hose sections. Avoid routing the hose below its 7/8-inch minimum bend radius to prevent flow restriction or kinking. Inspect the hose regularly for abrasion, chemical swelling, or deformation at connection points, as polyurethane hose in high-cycle environments can develop fatigue at the ends over time.
