This part of ISO 15171 specifies dimensions, performance requirements, and test procedures for diagnostic couplings with an M16 × 2 connection end that can be connected under pressure without tools to a maximum pressure of 40 MPa (400 bar) providing following stud ends:ISO 6149-2 - M14 × 1,5;ISO 9974-2 - M14 × 1,5;ISO 1179-2 - G 1/4;ISO 11926-2 - 7/16-20 UNF.The dimensions of the coupler counterpart are specified. The coupling is designed for use in hydraulic systems that use mineral oils.NOTE The use of this coupling with fluids other than mineral oil requires an agreement between the supplier and the purchaser.Couplings in accordance with this part of ISO 15171 may be used at a maximum working pressure of 63 MPa (630 bar). The working pressure depends upon the materials, design, working conditions, application, etc.Cross References:ISO 724ISO 965-1ISO 1179-2ISO 1629ISO 5598ISO 6149?2ISO 9227ISO 9974-2ISO 11926-2ISO 18869ISO 19879ISO 1179-1ISO 6149-1ISO 9974-1ISO 11926-1All current amendments available at time of purchase are included with the purchase of this document.
