Hydraulic Quick-Connect Couplings
Hydraulic quick-connect couplings create a fluidtight seal to maintain pressure and allow equipment changes in fluid and gas transfer, tool assembly, diagnostics, and other tasks that require frequent swapping out of equipment.
Quick Couplings have two parts: a coupling body (socket or female end) and a coupling plug (male end) that connect hydraulic lines to tools or equipment. Coupling connection types include push-to-connect, pull-to-connect, threaded connections, and universal interchanges. Couplings control spills, air inclusion, and disconnects with special features such as flush-face designs, self-sealing poppet valves, single- or double-shutoff valves, and sleeves (automatic, manual, locking).
What are ISO 7241 A Quick Couplings?
ISO A quick coupling is a quick coupling that meets the requirements of ISO 7241 A series for dimensions requirements. The ISO 7241 standard not only specifies the connection dimensions requirements but also the flow rate, working pressure, burst pressure, fluid loss during disconnecting and connecting, etc., depending on the performance of the carbon steel material body. ISO A quick-release couplings are quick-release couplings that meet the requirements of the ISO 7241 A series of connection dimensions. Other requirements may not necessarily meet the ISO 7241 standard, depending on the material of the quick coupling.
Compatible with PARKER 6600 Series, FASTER ANV Series, AEROQUIP 5600 Series and HANSEN HA 15000 Series.
ISO 7241-1A Quick Couplings
What are ISO 7241 B Quick Couplings?
ISO 7241-1B Quick Couplings
As the definition of ISO A quick coupling, ISO B quick coupling is a quick coupling with connection dimensions that meet the requirements of ISO 7241 B series dimensions. For ISO B quick couplings made of carbon steel, all parameters must meet or exceed the requirements of ISO 7241. For other materials, such as stainless steel or brass, only the dimensional requirements are met in order to achieve interchangeability in the connection, but other parameters do not necessarily meet the requirements of ISO 7241.

What are ISO 16028 Quick Couplings?
ISO 16028 sets the International Standards for quick coupling interchangeability, detailing the requirements for the performance of flat or flush face quick couplings used within a pressure of 20 MPa to 31.5 MPa. ISO 16028 does not include couplings which connect or disconnect under high pressure. The 16028 Series of flat face couplings offers superior, no-leak performance to a wide range of industrial uses.
