1. A system for centralizing a male quick connect nipple or a female quick connect coupling, the system comprising:
a housing;
the male quick connect nipple or the female quick connect coupling comprising a first circumferential part cone-shaped surface;
a hose connection, comprising a second circumferential part cone-shaped surface;
a first centralizing ring having a third circumferential part cone-shaped surface engaging the first circumferential part cone-shaped surface of the male quick connect nipple or the female quick connect coupling;
a second centralizing ring having a surface engaging with the second circumferential part cone-shaped surface of the hose connection;
a spring forcing the third circumferential part cone-shaped surface of the first centralizing ring and the first circumferential part cone-shaped surface of the male quick connect nipple or the female quick connect coupling, against each other, and forcing the surface of the second centralizing ring and the second circumferential part cone-shaped surface of the hose connection against each other; and
a rear sleeve in which the spring is positioned, the rear sleeve being arranged at least partly cylindrically around the spring,
wherein an end of the rear sleeve is configured to engage on an opposite side of the first circumferential part cone-shaped surface when the male quick connect nipple or the female quick connect coupling is pushed inwards into the housing.
