It gets really good when you put both together: The WEH® Coupling System consists of the Quick Connect Coupling WEH® TRC1 and the Plug-In Fitting WEH® TRN1.
Our coupling system can be connected on both sides to standard hydraulic hoses with fittings with BSP thread. Other connection sizes and types are possible. Feel free to ask our product experts for more information.

Here's another tip: Order the protective cap for the WEH® Flat-Face Quick Coupling System right away. Because clean work protects not only the coupling itself but your entire hydraulic system in this case.
This saves time, nerves, and money.
