ISO 16028 Flat Face Quick Release Couplings
Hydraulic Fluid Power – Flush-face Type, flat face, quick action release couplings for use at pressures of 20 Mpa (200 bar) to 31,5 Mpa (315 bar).In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure with an enclosed circuit. Quick Couplings are used to join or separate quickly fluid conductor lines, without the use of tools or special devices.Flat Face Quick Couplings are no-spill design and widely used in skid steers, tractors and some hydraulic pressure tools.
To choose the right quick couplings, you need to check the right body size for your hydraulic applications. In the ISO 16028:1999 standard file, you can see they have listed 6 different body sizes. For users, you can recognize the body size by measure the dimension of diameters from the male part.
Threads are used to connect the quick coupling to the hydraulic hose and the hydrualic devices. Usually the Male part connect to the hydraulic hose, and the female part connect to the hydraulic devices. Then when the quick coupling connect, the hydrualic enclosed circuit can works. and when disconnect the quick couping, the valves on the quick coupling will stop the liquid leak and make the hydraulic circuit cut. then you can change the attachments or overhaul the hydraulic devices etc.Users have to choose the right the threads to match your hydraulic fittings’ threads and the threads on your hydraulic device.Usually hydraulic devices will use the Pipe threads, they are designed special for fittings and pipe connecting. NPT/NPTF, BSPP or BSPT are normal options in different countries. And SAE or Metric threads will be used in some special requirements.
The ISO standards specifies the interface dimensions for interchangeablility and specifies the performance requirements, the quick couplings produced with this ISO standard from different brands can be interchanged.

Flat Face Quick Release Couplings have very wide usage in lots of hydraulic applications. As a small manufacturer of hydraulic quick release couplings, we did not supply our quick couplings to the hydraulic devices manufacturers, our main customers usually use our quick couplings as a quick-wear part replacement, we can get some feedback about where the quick coupling used.
For example, 1/2″ body size Flat Face quick couplings are widely used in lots of Skid Steer loaders,tractor, snow plow, brands like Bobcat,Kubota. 1/4″ body size flat face quick couplings used on Portable Car Lift, such as the brand QuickJack
frequently asked questions
The body is carbon steel, the spring, the valve is stainless steel 304, the seal ring is FKM. Carbon steel body can supply better working pressure, but they need to be plated by Zn or Zn-Ni alloy. FKM can supply better working temperature and support more liquid.
usually you need to check the body size, thread type and size. For example Bobcat skid steer, you may need a 1/2″ body size, NPT 1/2 Thread flat face quick couplings.
