Hi-tech Duravent 033701500001 Vacuum Duct Hose 1.5in Id 25ft

Product Description

The HI-TECH DURAVENT 033701500001 is a thermoplastic vacuum duct hose designed for demanding suction and transfer applications in industrial and commercial environments. With a 1.5-inch inside diameter and a 28 Hg vacuum rating, this hose maintains structural integrity under sustained negative pressure. It handles a maximum working pressure of 10 psi and operates across a temperature range of -40 to 250 degrees F, making it suitable for year-round service in variable conditions. Licensed trades and industrial technicians install this hose where consistent, flexible conveyance of dry bulk materials or process air is required. The hose weighs 5 pounds for the 25-foot length and features a tight 1.5-inch bend radius for routing in confined spaces.

This hose is specified for pellet transfer applications, including pneumatic conveying systems that move plastic pellets, wood pellets, or similar dry bulk materials. The 25-foot continuous length reduces the number of couplings needed in a run, which lowers potential leak points. The black thermoplastic construction resists acid, alkali, oil, and solvent contact, broadening its usefulness in facilities where incidental chemical exposure is possible. It suits both fixed-installation and portable vacuum system setups in industrial, agricultural, and light manufacturing environments.

Key Features

• 28 Hg vacuum rating supports strong sustained suction without hose collapse
• 1.5-inch inside diameter and 1.625-inch outside diameter for precise coupling selection
• Rated from -40 to 250 degrees F for cold-start and elevated-temperature service
• 1.5-inch bend radius allows tight routing in confined or congested installations
• Resistant to acid, alkali, oil, and solvents for use near chemical exposure
• 25-foot continuous length minimizes the number of inline fittings required

Compatibility

Designed for pellet transfer systems and pneumatic vacuum conveyance applications requiring a 1.5-inch ID thermoplastic hose with a 28 Hg vacuum rating and 10 psi maximum working pressure.

Installation Notes

Power down and de-energize the vacuum system fully before disconnecting or replacing hose sections. Verify that all end fittings and clamps are rated for the hose outside diameter of 1.625 inches before securing connections. Avoid kinking below the 1.5-inch bend radius, as deformation at connection points can reduce vacuum integrity. Follow applicable facility safety and pneumatic conveying codes when routing hose through walls, floors, or equipment enclosures.
