Clean break quick couplings for railway SPI

The non-spill, flat face design of these specialized 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. A large number of locking balls make locking quick, 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.

Applications: Hydraulic brake circuits, hydraulic tilting circuits, brake calipers, pressure accumulators, hydraulic pressure unit
