This vacuum adapter will slide over the end attachment of most vacuum systems that come with a 1-1/4 to 1-3/8 in hose. It is NOT threaded. The black adapter piece should slide over and create a tight seal with the vacuum hole. We recommend purchasing SurfPrep's Vacuum Hose to screw into this vacuum adapter.
