4-3-2 Using Quick-Change Couplers and Flexible Material Hose
You can attach a quick-change coupler or standard tube coupler to the tube at
either end of the flexible material hose. Make sure that the material flow is in
the direction of the arrows on the flexible material hose. The tube on each end
of a flexible vacuum hose should fit the tube coupler for the system. You can
also fit a quick-change coupler to either tube.
If your system requires a quick-change rack, hold the rigid tubing in place with
U-clamps. Mount male quick-change couplings on the rigid piping of a quick-
change rack. As your installation requires, bolt the rack in position to the wall
or floor before attaching the tubing.
Mount female quick-change couplers on the flexible hose of a quick-change
rack, allowing the ease and flexibility of selecting material flows or vacuum
flows, depending upon the requirements of your system design.
