3M 7000045311 Vacuum Hose Adapter 1 to 1.5 Inch Id

Product Description

The 3M 7000045311 is a vacuum hose adapter designed to connect a 1-inch ID vacuum hose to a 1.5-inch ID vacuum hose. It features a 1-inch friction fit barb on one end that inserts into the inner diameter of the smaller hose, and a 1.5-inch friction fit barb on the opposite end that inserts into the larger hose. This adapter is used in vacuum system setups where two hoses of different diameters must be joined in-line. HVAC technicians, contractors, and service professionals use this type of fitting when assembling or extending vacuum hose runs with mixed hose sizes.

This adapter is suited for use with portable vacuum systems, shop vacuums, and dust collection setups common in HVAC, construction, and general trade service environments. It is a practical solution when connecting equipment or accessories that use different hose diameter standards. The friction fit design requires no tools for attachment, making it a straightforward field connection.

Key Features

• Connects 1-inch ID vacuum hose to 1.5-inch ID vacuum hose
• Friction fit barb on each end — no clamps or adhesives required
• Barbs push directly into the inner diameter of each hose for a secure fit
• Compact adapter format for in-line hose connections

Compatibility

Designed as an in-line adapter for vacuum hoses with a 1-inch ID on one side and a 1.5-inch ID on the other side. Compatible with friction fit barb-style hose assemblies of the corresponding diameters.

Installation Notes

No tools are required for installation. Firmly push each barbed end into the corresponding hose ID until fully seated. Ensure the hose material is in good condition and free of tears before connecting, as a damaged hose wall may reduce friction fit retention. Disconnect the vacuum source before making or breaking any hose connections.
