WEH quick couplings

WEH's hand-operated TW17, TW18 and TW19 quick couplings make a leak-free connection to a thread without any screwing. How the clamping jaws work, what pressure the standard couplings take, and where they earn their keep in pressure and leak testing.

For pressure and vacuum testing of tubes, hoses and test pieces with male threads. The NONOX WEH FE coupling connects hoses, tubes and male-threaded parts quickly and trouble-free, with a perfect seal. With its elastomer sealing surface, the FE coupling is the most suitable solution for round profiles.

Top quality – maximum SAFETY. WEH offers a range of certified products for the safe and simple refuelling of CNG-powered vehicles: fuelling nozzles and fuelling guns, receptacles, breakaway couplings, check valves, filters, hoses. WEH® technology for the fast and safe refuelling of CNG-powered vehicles.

REFRIGERATION AND AIR-CONDITIONING TECHNOLOGY. Why bother with all that screwing about? Connect in a single movement! The WEH® range is wide, including NONOX stainless and acid-resistant versions, for the safe and efficient filling, testing and recovery of refrigeration equipment. A few application examples:

WEH has developed a NONOX stainless and acid-resistant quick coupling suitable for filling, function-testing and leak-testing closed cooling systems. The TW141 type connects easily to straight tubes, in NONOX stainless or acid-resistant versions – without any screwing. For applications where the tubes are difficult to reach, an extended version is available.

WEH® offers a wide product range of check valves for both general and special applications: liquid and gaseous media; a wide choice of materials and connection profiles, including NONOX stainless and acid-resistant versions; pressure range from 0.01 bar up to 1,000 bar.

Just as a top-performance machine deserves top-quality oil, so a top-performance NONOX stainless or acid-resistant quick coupling deserves a top-quality seal. WEH's development engineers design the WEH NONOX stainless and acid-resistant quick couplings to stand their ground in extreme industrial applications.
