Beswick snap type quick disconnect QDC-101-I (internal side) and QDC-102-E (external end), allows for quick tube connections and disconnections in a space saving package. Simply push the two halves together until they latch to connect, and slide the knurled sleeve on the internal side back to disconnect.  Internal O-ring seals ensure a leak tight operation.  This design incorporates a shut-off mechanism in the internal side (QDC-101-I). The QDC-101-I must be paired with a QDC-102-E or QDC-101-E half for a complete quick disconnect assembly.
