3M 7000045310 Vacuum Hose Adapter 1 to 2 Inch Id

Product Description

The 3M 7000045310 is a vacuum hose adapter designed to join a 1-inch inner diameter vacuum hose to a 2-inch inner diameter vacuum hose. The adapter uses friction fit barbs on each end: a 1-inch barb seats into the ID of the smaller hose, and a 2-inch barb seats into the ID of the larger hose. No tools or clamps are required for installation. This fitting is suited for use in workshop, industrial, or trade service environments where vacuum systems require a step-up connection between two hose sizes.

This adapter is used wherever a 1-inch vacuum hose must connect to a 2-inch vacuum hose in a single assembly. Typical applications include dust collection setups, vacuum extraction systems, and service tool configurations that use mixed-diameter hose runs. The friction fit barb design keeps installation straightforward and does not require adhesive or hardware to secure the connection under normal vacuum service conditions.

Key Features

• Connects 1-inch ID vacuum hose to 2-inch ID vacuum hose in a single fitting
• 1-inch friction fit barb inserts directly into the ID of the smaller hose
• 2-inch friction fit barb inserts directly into the ID of the larger hose
• No tools, clamps, or adhesive required for a standard friction fit connection
• Compact adapter format minimizes added length in the hose assembly

Compatibility

Designed for use with vacuum hoses having a 1-inch inner diameter on one end and a 2-inch inner diameter on the other end. No specific model compatibility data was provided by the manufacturer for this listing.

Installation Notes

Shut off and disconnect the vacuum system from power before making any hose connections or modifications. Press each barb firmly into the corresponding hose ID until fully seated to ensure a secure friction fit. Inspect the connection for air leaks before returning the system to service. Installation is typically performed by HVAC technicians, general contractors, or equipment service personnel familiar with vacuum system assemblies.
