Abstract: A fluid transmission fitting (100) is described comprising a flat-faced female coupler (47) with a frontal annular seal (400) to protect from the introduction of impurities, when uncoupled, during the step of coupling-uncoupling and when coupled to a flat-faced male coupler (48).

Abstract: A fluid transmission fitting (100) includes a female coupler (47) inserted within a hydraulic feeding block (1), and a male coupler (48), which can be coupled to the female coupler (47). The hydraulic feeding block (1) includes at least one hydraulic line (49) and a draining line (50), and a lever (4) integral with a cam (7) adapted to relieve the pressure from a chamber (54) inside the female coupler (47) and adapted to uncouple the male coupler (48) from the female coupler (47). The female coupler (47) including a pressure relief valve (51), which puts the chamber (54) into connection with the draining line (50).

Abstract: A fluid transmission fitting (100) includes at least two female couplers (47) inserted within a hydraulic feeding block (1), and at least two respective male couplers (48), which can be coupled to the female couplers (47). The block (1) includes at least two hydraulic lines (49) and at least one draining line (50), and a lever (4) integral with an independent member (82, 83) cam (7) adapted to relieve the pressure from a chamber (54) inside each female coupler (47) and adapted to uncouple the male coupler (48) from the respective female coupler (47). Each female coupler (47) includes a pressure relief valve (51), which puts the chamber (54) into connection with the draining line (50).
