Hi-tech Duravent 213200752250 Vacuum Duct Hose 3/4 in

Product Description

The HI-TECH DURAVENT 213200752250 is a polyurethane vacuum duct hose designed for light-duty vacuum and low-pressure air transfer applications. It carries a 30 Hg vacuum rating and a 40 psi maximum working pressure, making it suitable for industrial, HVAC, and shop vacuum systems that demand flexible, transparent hose construction. The clear opaque wall allows technicians to visually confirm flow and detect blockages without disconnecting the line. At 3/4 inch inside diameter and a 1.1 inch outside diameter, it fits standard vacuum hose fittings across a range of equipment. The 50-foot coil length reduces the need for mid-run splices on longer runs.

This hose is suited for residential and light commercial HVAC installations, shop vacuum systems, dust collection setups, and portable extraction equipment. The polyurethane construction handles a working temperature range of -20 to 180 degrees F, allowing use in unheated mechanical spaces, cold-climate installs, and applications near moderate heat sources. Plumbing and HVAC technicians commonly use this hose for equipment drainage, vacuum evacuation assist lines, and low-pressure pneumatic transfer where flexibility and visual monitoring are required.

Key Features

• 30 Hg vacuum rating supports reliable suction in vacuum and extraction applications
• 40 psi maximum working pressure for low-pressure air and fluid transfer
• Clear opaque polyurethane wall allows visual flow inspection without disconnection
• Wide temperature range of -20 to 180 degrees F suits cold and warm environments
• 2.25 inch minimum bend radius maintains flow through tight routing paths
• 50-foot continuous length minimizes inline connections on longer runs

Compatibility

Designed as a general-purpose replacement or new-install vacuum duct hose for systems requiring a 3/4 inch ID polyurethane hose rated to 30 Hg vacuum and 40 psi working pressure.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or mechanical contractors. Shut down and de-energize any equipment connected to the vacuum or pressure circuit before routing or connecting this hose. Use barbed or clamp-style fittings rated for the application pressure and ensure all connections are secured with appropriate clamps to maintain the rated vacuum and pressure integrity. Avoid routing near surfaces that exceed the 180 degrees F maximum working temperature.
