Asymmetric hose coupling endform for fluid transfer assemblies

An endform connector comprising:

• a rigid tubular member having a first terminal end configured to be inserted into an inner channel of one end of a fluid transport hose, a second terminal end configured to be coupled with a fluid conveying structure, and a channel having an inner diameter extending from said first terminal end of said tubular member to said second terminal end of said tubular member providing a path through which a fluid is transported, said first terminal end comprising a stem portion extending a fixed distance from said first terminal end, and at least one sealing member extending radially outward from said stem portion forming a radially increasing surface having a tapered profile, said radially increasing surface having said tapered profile terminating in a rim exhibiting an asymmetric perimeter, said at least one sealing member also including a rearward surface lying in a plane perpendicular to or nearly perpendicular to the orientation of the tubular member, said rearward surface extending radially outward from the tubular member and terminating with said rim exhibiting said asymmetric perimeter, said stem portion configured to be sealably inserted into the inner channel of one end of the fluid transport hose to provide a leak-free fitting.
