Rotary unions are mechanical devices enabling one or more fluids to be transferred from a fixed part to a rotary part whilst ensuring a fully effective seal between the two parts. There are several types of rotary union in order to meet all our customers' needs.

Rotary unions can carry one or more fluids simultaneously, at different pressures and temperatures. Duff-Norton Europe rotary unions enable your fluids to be carried at between 0 and 700 bar (up to 1500 bar for certain special products), whilst permitting oscillatory motion or rotational movements of almost 5000 rpm. Our rotary unions can be bought in chemical nickel-treated steel (anti-corrosive treatment) or in stainless steel, or in any other material according to your needs.
