Flexaust 8011040025 Vacuum Duct Hose 4 in Id 25 Ft Pvc

Product Description

The FLEXAUST 8011040025 is a clear PVC vacuum duct hose designed for air and fume handling in light industrial, commercial, and HVAC ducting applications. Constructed from polyvinylchloride with a wall thickness of 0.02 inches, this hose delivers a maximum working pressure of 8 psi and a vacuum rating of 9 inches Hg. The flexible construction supports a bend radius of 3.3 inches, making it well suited for installations that require routing around obstructions. Licensed HVAC technicians, ductwork fabricators, and industrial service contractors are the primary installers of this product.

This hose is rated for operating temperatures from 20 degrees F to 160 degrees F, covering a wide range of seasonal and process conditions. The 4-inch inside diameter and 25-foot length make it a practical choice for central vacuum systems, dust collection runs, fume extraction lines, and general air conveyance ductwork in both residential and light commercial settings. Its clear body allows visual confirmation of flow and blockages without disconnecting the assembly.

Compatibility

Suitable for air and fume handling applications. Designed as an OEM-style flexible duct hose for use with central vacuum, dust collection, and fume extraction systems requiring a 4-inch inside diameter connection.

Installation Notes

Installation should be performed by a qualified HVAC technician or industrial ductwork contractor. Shut down and de-energize the associated air-handling or vacuum system completely before connecting or disconnecting the hose. Secure all end fittings with appropriate clamps rated for the working pressure and vacuum of the system. Inspect the hose routing to ensure the bend radius does not fall below 3.3 inches, which can restrict flow or cause premature wear.
