Abstract
A breakaway hydraulic coupler includes a coupler body assembly removably attachable to a fluid hydrant by a first lock member thereof. A sleeve assembly is connected to the coupler body assembly and includes a second lock member selectively movable into engagement with the first lock member to move the first lock member into locked position to attach the coupler body to the fluid hydrant. Upon an application of a load external to the hydraulic coupler exceeding a predetermined amount, the first lock member applies a sufficient force to the second lock member to cause a region of weakness of the second lock member to displace, allowing the first lock member to move to the unlocked position and the hydraulic coupler to detach from the hydrant.
