3M 7000045312 Vacuum Hose Adapter 1 to 1-1/4 Inch Id

Product Description

The 3M 7000045312 is a vacuum hose adapter designed to connect a 1 inch ID vacuum hose to a 1-1/4 inch ID vacuum hose. It uses a friction fit barb on each end — a 1 inch barb that pushes into the 1 inch hose ID and a 1-1/4 inch barb that pushes into the 1-1/4 inch hose ID. No tools or adhesives are required for installation. This adapter is a practical solution for HVAC technicians, restoration contractors, and other trades who need to join mismatched vacuum hose sizes during equipment setup or service work.

This adapter is suited for use with standard vacuum equipment where hose diameters do not match at connection points. Typical applications include portable vacuum and extraction systems used in HVAC service, duct cleaning, and general industrial or janitorial settings where a 1 inch hose must mate to a 1-1/4 inch hose or fitting. It is sold individually as a single unit.

Key Features

• Connects 1 inch ID vacuum hose to 1-1/4 inch ID vacuum hose
• Friction fit barb design on both ends — no tools required
• Pushes directly into the hose ID for a secure mechanical connection
• Compact adapter form factor for quick field use

Compatibility

Designed for use with standard vacuum hoses having a 1 inch ID on one end and a 1-1/4 inch ID on the other end. Compatible with typical friction fit vacuum hose systems used in portable extraction and vacuum equipment.

Installation Notes

Ensure both vacuum hoses are powered off and the vacuum unit is shut down before making hose connections. Push each friction fit barb firmly into the corresponding hose ID until seated. No adhesives, clamps, or specialized tools are required. Inspect the connection for a snug fit before resuming operation.
