Robust Solutions for Off-Highway Applications – WEH® Components for Construction, Agricultural & Forestry Equipment

Construction sites, fields, forests, or mines – in the off-highway sector, machines are exposed to extreme conditions every day: dirt, moisture, vibrations, and temperature fluctuations. Downtime is costly – and critical to safety. That’s why robust, reliable components are essential. WEH delivers exactly that: flat-face quick connect couplings for hydraulic lines, durable quick connectors for testing processes, and safe H2 and CNG refueling components for alternative drives. Our solutions have proven themselves worldwide – in construction and agricultural machinery, mining, and forestry.

Common applications

Pressure and leak testing

With WEH® quick connectors, you can test cylinders, lines, and valves quickly, safely, and without screwing – even at high pressures.

Connecting hydraulic lines

Our flat-face quick connect couplings ensure leak-free connections even under harsh conditions – for greater efficiency and environmental protection.

Refueling H2

WEH® Hydrogen components enable standard-compliant hydrogen refueling at 25 / 35 / 70 MPa – for sustainable mobility.

Refueling CNG

From receptacles to fueling nozzles: WEH® CNG components enable safe and easy refueling with natural gas and biogas.
