ISO 15171-2:2016

ISO 15171-2:2016 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.
