Describes dimensions for ports with ISO 228-1 threads for use with non-adjustable stud ends described in ISO 1179-2, ISO 1179-3 and ISO 1179-4 and with adjustable stud ends described in ISO 1179-3.

This part of ISO1179 specifies dimensions for ports with ISO228-1 threads for use with non-adjustable stud ends described in ISO1179-2, ISO1179-3 and ISO1179-4 and with adjustable stud ends described in ISO1179-3.

Ports in accordance with this part of ISO1179 are applicable for use with

• ISO1179-2 heavy-duty (S series) stud ends with type E sealing at working pressures up to 63MPa (630bar) and light-duty (L series) stud ends at working pressures up to 25MPa (250bar),

• ISO1179-3 light-duty (L series) stud ends with type G sealing at working pressures up to 31,5MPa (315bar) and ISO1179-3 light-duty (L series) adjustable stud ends with type H sealing at working pressures up to 20MPa (200bar), and

• ISO1179-4 stud ends with type B sealing at working pressures up to 40MPa (400bar) for the S series, up to 25MPa (250bar) for the L series, and up to 10MPa (100bar) for the LL series,

except for the G2 size port, which in hydraulic fluid power systems is used mainly with accumulators and for which ISO1179-3 and ISO1179-4 do not specify stud ends. The permissible working pressure depends upon size, materials, design, working conditions, application, etc.

Users of this part of ISO1179 should ensure that there is sufficient material around the port to maintain the pressure.

NOTE The introduction of this part of ISO1179 gives recommendations for ports and stud ends to be used for new designs in hydraulic and pneumatic fluid power applications.
