Parker ISO Couplers

Now more than ever, modern hydraulic systems demand faster changeovers, cleaner operation, and safer connections. That’s why flat‑face ISO 16028 quick couplers have become the preferred solution across mobile and industrial hydraulics.

The Hidden Cost of Traditional Hydraulic Couplers

Older ball‑valve or poppet‑style couplers get the job done, but they often introduce problems that quietly impact performance and uptime. While easier to source, traditional couplers are prone to spills and fluid loss, increased contamination, slower connections, and safety risks. 

 

What Flat-Face ISO 16028 Couplers Do Differently

Cleaner Connection. Less Mess. 

The flush, non‑spill valve design minimizes fluid loss during connect and disconnect, resulting in cleaner work areas, less fluid waste, and reduced risk of contamination.

Less Air. Less Contamination. 

Because the couplers feature a flat surface on both the male and female ends, the sealing surfaces meet flush, reducing air inclusion and helping to keep dirt out — a critical factor in extending the life of your hydraulic components.

Faster, Easier Operation. 

ISO 16028 couplers feature a push‑to‑connect design, allowing quick, one‑handed connections without tools.

Built for Global Compatibility. 

By meeting ISO 16028 standards, these couplers are interchangeable across manufacturers, making them easy to source, replace, and standardize.

 

What About Trapped Pressure

One of the most common frustrations in hydraulic systems is residual pressure that remains in the line after shutdown. Under these conditions, traditional couplers can make reconnection difficult and unsafe.

Parker’s FEC Series nipples are designed to allow connection under residual pressure, helping operators get equipment back up and running without delays or workarounds, preventing stalled jobs and unnecessary downtime.

 

Parker FEM & FEC Series

Parker’s FEM and FEC series combine ISO compliance with design features built for demanding environments:

Durable steel construction with zinc‑nickel plating for corrosion resistance

Flat‑face, non‑spill valves to support cleaner operation

Optimized flow performance and improved pressure capability in the latest redesigns

PVC dust caps to protect sealing surfaces in harsh field conditions

These details make a difference in applications where couplers are exposed to dirt, vibration, frequent use, and high pressures.

 

Where Flat-Face ISO Couplers Deliver the Most Value

Flat-face ISO couplers are ideally suited for: 

• Construction and utility equipment with frequent attachment changes

• Mobile hydraulics operating in dirty or outdoor environments

• Industrial systems where contamination control is critical

• Maintenance operations focused on reducing downtime and cleanup

 

Choosing the Right Coupler Matters

Selecting the right coupler depends on the application. Factors like flow requirements, pressure ratings, connection frequency, and environmental exposure all play a role.
