Continental Contitech 20448190 Material Handling Hose

Product Description

The CONTINENTAL CONTITECH 20448190 is a urethane dry material handling transfer hose designed for industrial bulk material conveyance applications. With a 4-inch inner diameter and 4.74-inch outer diameter, it provides high-flow capacity for moving dry granular and powdered materials through transfer systems. The hose carries a 30 psi maximum working pressure rating and a 29 inches Hg vacuum rating, making it suitable for both pressure and suction transfer configurations. A 7-inch minimum bend radius keeps the flow path open during installation in tight routing scenarios. Urethane construction delivers abrasion resistance appropriate for demanding dry material service. Licensed HVAC, mechanical, and industrial contractors install this hose as part of pneumatic conveying and bulk transfer systems.

This hose is used in industrial and commercial environments where dry bulk materials such as grain, pellets, powders, or granulates are transferred pneumatically or by gravity feed. It is rated for a continuous temperature range of -40 degrees F to 158 degrees F, supporting year-round use in both heated and unheated facilities. The hose is sold in 1-foot increments with a 5-foot minimum cut length and is available from a 100-foot coil. Minimum order quantity is 5 units. The black urethane construction resists wear from abrasive particulates flowing at high velocity through the bore.

Key Features

• 4-inch ID with 30 psi maximum working pressure and 29 inches Hg vacuum rating
• Urethane construction for superior abrasion resistance in dry bulk material service
• Wide temperature range: -40 degrees F to 158 degrees F
• 7-inch minimum bend radius for flexible routing in tight installations
• Sold in 1-foot increments from a 100-foot coil with 5-foot minimum cut length
• Black outer finish for UV and environmental resistance in industrial settings

Compatibility

Designed as an OEM-style replacement or original installation hose for industrial dry material pneumatic conveying and bulk transfer systems requiring a 4-inch ID flexible urethane hose rated at 30 psi.

Installation Notes

Installation of bulk material transfer hose should be performed by qualified industrial or mechanical contractors familiar with pneumatic conveying systems. Depressurize and lock out the conveying system completely before disconnecting or replacing any hose section. Verify that all clamps, couplings, and fittings are rated to at least the system working pressure before returning the line to service. Do not exceed the 7-inch minimum bend radius, as kinking will restrict flow and accelerate hose wear at the deformation point.
