  • Patent number: 5524663
    Abstract: The present invention provides a vacuum tube shut-off 10 for shutting off vacuum air flow between coating removal power tools 36 and a vacuum source 34. The vacuum tube shut-off 10 includes a vacuum tube 12 in vacuum air flow communication with the power tool 36 and the vacuum source. The vacuum tube 12 has a slot 26 transverse to the air flow direction through the vacuum tube 12. An air flow block 16 is removably insertable into the vacuum tube 12 through the slot 26 to prevent air flow through the vacuum tube 12. A self clamping stopper or O-ring 14 circumscribes the outside of the vacuum tube 12 to sealingly engaging the vacuum tube 12 to prevent air flow through the slot 26 when the air flow block 16 is removed from the slot 26.
