3M 7000045005 Vacuum Hose Adapter 1 in X 1.5 in Od

Product Description

The 3M 7000045005 is a vacuum hose fitting adapter designed to connect vacuum hoses with differing thread and hose diameters. It features a 1 inch internal hose thread on one end and a 1.5 inch OD hose connection on the other, allowing techs to bridge mismatched vacuum hose fittings without improvising a seal. The adapter weighs 0.12 pounds, making it a lightweight component suited for toolbox or service van inventory. HVAC technicians, plumbers, and facility maintenance professionals commonly reach for this adapter when joining vacuum equipment to hoses that do not share a common thread or outer diameter spec.

This adapter is used wherever vacuum hose connections must transition between a 1 inch internal thread fitting and a 1.5 inch OD hose. Typical install scenarios include vacuum pump setups, wet-dry vacuum equipment, and industrial suction systems where hose sizing varies by tool or task. The adapter is sold individually and is suitable for both shop and field use across HVAC, plumbing, and general mechanical trades.

Key Features

• 1 inch internal hose thread inlet for threaded vacuum hose connections
• 1.5 inch OD hose outlet for slip-fit or barbed hose attachment
• Lightweight construction at 0.12 pounds for easy portability
• Sold as an individual unit for targeted replacement or inventory restocking

Compatibility

Designed as an OEM-style fitting adapter compatible with vacuum hose assemblies requiring a 1 inch internal thread to 1.5 inch OD hose transition.

Installation Notes

Installation requires no special tools beyond hand tightening for threaded engagement. Ensure the vacuum source is fully powered down and depressurized before disconnecting or replacing hose fittings. Verify thread engagement is secure and the OD hose slip fit is fully seated before resuming vacuum operation to prevent air leaks that reduce system performance.
