The non-spill, flat face design of these specialized quick couplings ensures that there is no loss of liquid on disconnection and no ingress of air into the circuit on connection. Long guiding of the plug into the socket provides constant tightness, even under harsh conditions. The ball locking is quick, easy, safe, and strong enough to withstand the most severe conditions of vibration, oscillation, etc. Chloroprene protection prevents external agents such as water or dust from penetrating.
