1" ID x 6 Feet 1" External Hose Thread
Use this externally threaded hose to connect 3M dust extraction random orbital sanders to your house or cannister vacuum.
This hose is sized with a 1" internal diameter to slide onto 1" hose fittings.
Its external spiral surface fits 1" internally threaded hose fittings.
While, in theory, this 1" external thread hose can screw into the exhaust of your 3M sander, in practice, it is mush easier to use a #28304 hose adapter so you don't have to twist the hose.
One end of the hose screws fits onto an adapter on the tool
The other end will accept various adapters to match your house or cannister vacuum system
Hose can be cut to length
