Abstract

A hybrid male coupling member adaptable to couple with at least two types of female coupling members includes a one piece integrally molded housing having a front engagement wall, a fluid path being defined by an inner wall. The inner wall has an engagement section disposed proximate a front end of the housing. The male coupling member further includes a first groove being disposed around an outer wall of the housing and a second groove being disposed in the first groove. When the male coupling member couples with the first female coupling member, the engagement section of the male coupling member engages with a spring-biased poppet of the first female coupling member and forces the poppet toward a back end of the first female coupling member so as to allow the fluid to flow therethrough, a plastic clip being received in the first groove to latch the male coupling member and the first female coupling member together. When the male coupling member couples with the second female coupling member, the front engagement wall of the male coupling member engages with a spring-biased poppet of the second female coupling member and forces the poppet toward a back end of the second female cou…
