male cone housing cavity 53 in communication or fluidly coupled to and proximate to the system conduit not shown the male coupling assembly 1 has a male cone housing 5 the male cone housing 5 is formed to be receivably inserted or nested into a female coupling 3 such as the one embodied in fig2 the male cone housing 5 in the embodiment of fig1 is substantially a right circular cylinder shape the male cone housing 5 is not limited to a right circular cylinder shape the male cone housing cavity 53 is formed by the male cone housing 5 a male seal ring 15 is formed or disposed on the male cone housing 5 the male seal ring 15 is formed such that it can receivably mate or seal with a male cone housing seal 17 the male seal ring is also formed in order to couple with a seal mechanism 43 see fig4 and fig8 the male seal ring 15 is made of a material that has a surface hardness less than the second washer 55 of the seal mechanism 43 see fig7 with a soft surface hardness the male seal ring 15 can deform around the second washer 55 to form part of a high reliability seal 51 to be discussed in more detail below see fig4 the male cone.
