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.

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.

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.
