WEH® TRC1-S1 Flat-Face Coupling, 500 bar, G1/4" female thread, DN 6.3


After 5 Substitutions, It`s Over!But Not with WEH® Flat-Face Couplings.

For hydraulic applications in which lines are frequently connected and disconnected, a quick release coupling is an effective solution.

The WEH® Flat-Face Quick Connect Coupling offers just that – and even more. These couplings withstand hard impacts with dynamic force (hammer strikes up to 8 tons) and sudden changes in flow direction.

The WEH® Flat-Face Couplings feature an impressively long service life, high resistance under “heavy-duty” applications as well as high bursting and operating pressure. One unique aspect: The TRN1 plug-in fitting is optimized during the manufacturing process using the case hardening method. In this way, we achieve maximum possible surface hardness on the entire front part of the fitting. This is a major advantage in challenging applications.

The WEH® Flat-Face Quick Connect Couplings are not only tough, they are also good for the environment. In contrast to the old ISO-A or ISO-B couplings with conical valves, the loss of media is significantly lower when changing with a flat-face coupling. Our flat-sealing system ensures that no hydraulic oil leaks out. This is not only good for the environment, it is also good for your budget. No cleaning costs, no refills of hydraulic oil.

With WEH® Flat-Face Quick Connect Couplings, your work is fast, easy, clean and safe. Our couplings significantly exceed the requirements of the applied standard ISO 16028 in many aspects.
