1. A liquid manure hose coupler end, comprising:
a body defining a body longitudinal axis terminated at a first body end and a second body end distal to said first body end, and an exterior wall circumscribing an interior passageway passing entirely through said body in a longitudinal direction;
at least a first hose rib and a second hose rib, each forming a part of said body exterior wall and configured to engage with a hose and each defining a respective hose rib outside diameter;
at least a first hose groove, a second hose groove, a third hose groove, and a fourth hose groove, each forming a part of said body exterior wall and configured to engage with a hose and each defining a respective hose groove outside diameter;
a first sloped transition half rib adjacent to said first body end forming a part of said body exterior wall and configured to engage with a hose and defining a first sloped transition half rib outside diameter;
a collar separating rib forming a part of said body exterior wall and configured to engage with a hose and defining a collar separating rib outside diameter;
said first hose rib intermediate between said first sloped transition half rib and said collar separating rib and said second hose rib more distal from said first body end than said collar separating rib;
a sleeve seal ring adjacent said second body end and configured to form a seal between a sleeve extending from said liquid manure hose coupler end and said liquid manure hose coupler end;
a first collar securing said hose to said first sloped transition half rib, said collar separating rib, said first hose rib, said first hose groove, and said second hose groove, said first sloped transition half rib defining a tapered transition from said first sloped transition half rib outside diameter to said first hose groove outside diameter and said collar separating rib defining a tapered transition from said collar separating rib outside diameter to said second hose groove; and
a second collar separate from, immediately adjacent to, and configured to function independently of said first collar, said second collar securing said hose to said collar separating rib, said second hose rib, said third hose groove, and said fourth hose groove;
said first sloped transition half rib outside diameter and said collar separating rib outside diameter each greater than said first hose rib outside diameter, said collar separating rib outside diameter greater than said second hose rib outside diameter, said first hose rib outside diameter greater than said first hose groove outside diameter and said second hose groove outside diameter, and said second hose rib outside diameter greater than said third hose groove outside diameter and said fourth hose groove outside diameter.
