Quick coupling fittings are composed of a jack with hose end connector and a threaded male coupler which connects itself to the jack.

They are fixed by a ball ring pushed by a spring. A nitrile rubber seal guarantees a perfect vacuum seal.

This type of fitting allows the two components to rotate freely at a low speed and to rapidly couple and disconnect by manually acting on the jack reeded ring nut.

These fittings are fully made with brass and are available in various sizes.
