Parker offers a selection of dust plugs and caps for their
hydraulic quick couplings. Most series shown in this section have a dust plug
and cap specifically designed to be used with that style of coupling. Dust plugs
and caps serve a twofold function. They keep the mating surface clean and free
of contamination and protect the critical mating elements of the coupling halves
when they are disconnected. In this way the nipple is protected from damage that
would make the total coupling unusable.
Protective dust plugs and caps play a crucial role in
the use of quick couplings and no purchase of a hydraulic quick coupling is
complete without the selection of an appropriate dust plug and cap. When
ordering the dust cap/plug body size must correspond to that of the coupler or
nipple.
