Zusammenfassung:PNEUMATIC MANIFOLD QUICK COUPLING A quick pneumatic coupling particularly well adapted for use in a folding agricultural planter comprises a rigid plastic funnel mounted to the end of a first conduit and a flexible and resilient rubber flange member mounted to a second conduit. The inner surface of the funnel forms a sealing surface which is contacted by the flange when it is inserted into the funnel. The coupling can be automatically coupled and decoupled by pivotally inserting and withdrawing the flanged member into and out of the receiving funnel.
