The two ends are open and closed, the two ends are open and the single way open and close.

Opening and closing of the two ends


When it is not linked, when the female's ring is moved to the other end, the stainless steel ball rolls outwards automatically, and the daughter body is disconnected due to the action of the spring force of the common valve and the daughter body, and the valve of the daughter body is closed with the parent valve, and the fluid flow is stopped instantly.

Link: when the body is inserted into the matrix ring, back to the original position under the action of a spring, a steel ball rolling lock body are tightly connected, and parent and progeny to promote each other and open the valve, fluid flow, O ring can completely block the leakage of fluid.

Opening at both ends


No link: when the female's ring is pushed to the other end, the steel ball rolls outwards automatically, so the daughter is removed. Due to the absence of valves between the body and the parent body, the fluid flows outwards.

Link: when the body is inserted into the matrix, the spring force ring is pushed to the previous position caused by steel ball locking, fluid flow, the O ring to prevent fluid leakage

Single path opening and closing

No link: when the female ring is moved to the other end, the stainless steel ball automatically rolls outward, and the body is spricked open by the reaction force of the valve spring, and the valve can be automatically closed to stop the fluid flow.

Link: when the body is inserted into the maternal side ring when the valve is opened to fluid flow, the force of the spring washer is pushed back to the original position, stainless steel beads will lock to ensure that the child / parent connection, which can prevent the leakage of washer fluid.
