General technical guidance
The following explains this component family; it is not a specification or approval of the supplied WH variant.
Coupling retention and mating
Universal air couplings require the correct mating head and sealing insert. Connection retention and hose attachment are separate checks. A similar-looking head does not establish compatibility or the approved service of an unidentified coupling.
