3M 7000118692 Mini Air Line Extension 3/8x5 in

Product Description

The 3M 7000118692 is a mini air line extension designed for use with 3M Random Orbital Sanders equipped with Self-Generating or Central Vacuum systems. The extension measures 5 inches in length and moves the coupling connection away from the exhaust tube, reducing interference during sanding operations. It connects via a 1/4-inch NPT fitting that attaches directly to the sander body. This small but functional accessory is installed by professional body shop technicians, finishing specialists, and industrial sanders who need better hose routing and clearance at the tool connection point.

This air line extension is intended for use with 3M Random Orbital Sanders that feature Self-Generating Vacuum or Central Vacuum configurations. It is suited for production finishing environments where repeated tool use makes ergonomic hose management a priority. The extension is sold individually and is appropriate for both fixed-station and mobile finishing setups in automotive, woodworking, and industrial surface preparation applications.

Installation Notes

Disconnect the air supply and relieve line pressure before attaching or removing any pneumatic fittings.
