Nilfisk and Tellus 32mm Rubber Muff Kit For GM80 Vacuum Cleaner Hoses
Original Nilfisk 32mm rubber muff kit for the best quality tapered rubber, braided, or plastic vacuum cleaner hoses, usually fitted to the Nilfisk GM80
They are usually sold in commercial situations or used on older domestic units, especially the Tellus branded Nilfisk products which are sold in New Zealand.
It meant for extreme flexibility and easy removal of the bent tube for removing blockages or for joining together lengths of hose.
The tapered hose was meant to reduce hose blockages occurring away from the operator where they would be oblivious to it. If an item was of sufficient dimensions to enter the pipe, there was a good chance it would continue unhindered to the dust container as the hose diameter increased. Otherwise, it could be easily retrieved out of this muff arrangement.
To easily dis-assemble, compress the joint in one hand and slip a ring off with the other hand.
Once you've done it a few time, you'll get the knack!!
