Thanks to the continuous extension of the CNG filling station network for self-service operation, refuelling with natural gas is enjoying increasing acceptance.
The requirements demanded of components for CNG filling stations are very stringent in terms of safety, reliability and functionality.

Wherever straight tubes and bores have to be leak, pressure or vacuum tested, WEH® Connectors are the perfect tool. WEH® Test Connectors reliably seal internal tubes - of both small and large diameter.

Pneumatic leak tests are the method of choice in many industries and must be quick, reliable and of course leak-free. WEH® Test Connectors are the perfect tool. The device is attached in seconds to the component to be tested, without any need for time-consuming screw connections. The use of WEH® Test Connectors makes additional sealing components redundant.
