Vacuum Cups

Fitting Assembly

Secure a block tee or other suitable pipe fitting in a vise to make a simple fixture as shown in the illustration.

Screw the cup fitting into the fixture about 2 threads by hand.

Dip your finger into a small container of water and wipe a few drops onto the fitting flange and into the top chamfer and bore of the vacuum cup.

Use only water. Do not use soap or oil. Water will quickly evaporate and leave no residue to later effect performance.

Invert the suction cup and place it onto the flange as shown. Grasp the far side of the cup and pull it over the flange while pressing downward. After the cup snaps ove the flange, rotate the cup on the fitting half a turn to make sure it is properly seated.
