This provides a low cost, high quality alternative to multiple sizes of individual vacuum chucks, while allowing the user to quickly move from one size cup to another.  The cups (2" PVC pipe couplings) are inserted into the precisely machined groove in the face of the hub, sealed by an O-ring in the bottom of the grove, and retained securely with 6 set screws around the perimeter.  Hubs are available in 1"x8, 1.25"x8, and M33x3.5 spindle thread sizes to accommodate most popular lathes.  Learn more about the Precision Vacuum Hub products on the vacuum hubs page.
