Test Point Fittings for diagnostic pressure purposes of hydraulic fluid power, there are two types: one is test coupling not for connection under pressure, meet ISO 15171-1; another one is hydraulic test couplings, with M16x2 end for connection under pressure, meet ISO 15171-2; Test point adaptor also meet SAE J1502 standards.

ISO 15171-1 specifies test procedures for the male quick action coupling with M14*1.5 end to ISO 6149-1 port, maximum working pressure of 40 MPa, used in hydraulic systems quick test.

ISO 1517-2 specifies test procedures for diagnostic coupling with M16*2 connection, under pressure without tools to a maximum pressure of 60 MPa, providing following stud ends:

ISO 6149-2 M14*1.5

ISO 9974-2 M14*1.5

ISO 1179-2 G1/4

ISO 11926-2 7/16-20 UNF
