[QUOTE="ajsdwilson, post: 23480, member: 2515"] Sorry...a male is known as male, plug, nipple, or adapter (Depending on the industry you are in) and a female is known as female, receiver, or coupler. All flatface, since their inception, use the male valve seal as the main sealing method for the entire coupling when they are connected. There are occasions where the coupler can leak in the connected state, but this isn't a very common problem. Since the male valve seal serves two purposes, to seal the nipple valve when disconnected and the entire coupling when connected, there is a lot relying on this seal. The conditions of certain death for a flushface coupling are dirt/grit and side-load. You want to be sure that these are relatively clean when you make a connection and you want to be sure that the coupling is not side-loaded during operation...either of these conditions will kill the seals. Seal technology has really improved over the past couple of years and leaking is becoming less of an issue. One other killer...screwdrivers! When pressure is trapped in the coupling, there is a tendency to hit the valve to release the pressure - this damages the seals if the screwdriver makes contact with the seal or you end-up with a condition called nibbling as the pressure in the coupling blows by the seal when releasing the pressure, bits of the seal are removed by the pressurized fluid coming past the seal.
