Abstract: An example coupling device includes a main body with a fluid passage therethrough, a first end with an opening. A receptacle member is positioned within the main body about the fluid passage, the receptacle member being sized to receive a portion of a mating coupling device that is inserted through the opening in the first end. A deformable seal member is positioned within the receptacle member, the seal member including a primary sealing surface and a secondary sealing surface to provide fluid tight seals with the mating coupling device, the primary sealing surface being positioned to engage an end of the mating coupling device, and the secondary sealing surface being positioned in a perpendicular orientation with respect to the primary sealing surface to engage a side surface of the mating coupling device.
