DNP

DNP is D.N.P. Industriale S.r.l. of Brugherio, near Monza in Italy, which has made hydraulic quick-release couplings since 1985. The range covers flat-face couplings to ISO 16028, poppet and ball types built to the ISO 7241 profiles, and screw-to-connect couplings for high-pressure and impulse duty, in the sizes used on agricultural and earth-moving machinery and on industrial hydraulic circuits. Nothing is catalogued under this brand yet. When enquiring, give the coupling profile or standard you have to match, the body size and thread, the working pressure, and whether the connection has to be made with residual pressure trapped in the line - that last point decides which type of coupling will actually work on the machine.
