Click a part or its number. Drag to move, pinch or Ctrl + scroll to zoom. Arrows step through positions in the manufacturer's numbering (not an assembly sequence). The manufacturer's drawing shows the parts already pulled apart and gives no assembled positions; Vac & Air does not invent them. Positions were placed automatically from the manufacturer's numbering.

Select a part on the drawing or in the list to see its number, what it fits and where to get it. Turn on “select several” to build one quote for many parts.
