1 and stay away from open-closed: when you are not connected – when the ring moves to the other end of the matrix, Pearl stainless steel automatic rolling to the outside, a descendant and descendant of the matrix operation disconnect the common valve Spring forces forcing, valve closed and the mother of a descendant, instantly blocking the flow. Connections–When you insert maternal descendants, rings under spring back to its original position, keyboard scroll lock descendants closely connected, while parent and descendant of the valve to facilitate open, fluid flow,o-rings, completely blocking leakage of the fluid.

2 , open at both ends is not connected – when a mother's ring is pushed to the other side, ball automatically scrolls to the outside, so the descendants were moved out as descendant and parent do not have valves, fluid outflow outward. Connections–When you insert maternal descendants, ring is spring force pushing it to its previous position caused by steel ball locking, fluid flow, in whicho-rings to prevent fluid leakage.

3 , single line when not connected to an opening and closing – when the ring moves to the other end of the matrix, Pearl stainless steel automatic rolling outward, descendant, was bounced by reaction force of the valve spring, the valve automatically closes to stop fluid flow. Connections–when the descendant when the maternal side of the ring is inserted, the valve is opened causing fluid flow, power washer spring back into its original position, stainless steel bead lock to ensure that the child/parent connection inside the washer can completely block the fluid leakage.
