WEH® Connectors for Evacuating
Safe & efficient evacuation
Why use quick connectors for evacuation?
When evacuating circuits or gas cylinders, fast, absolutely tight connections are essential – especially with sensitive media, low temperatures or frequent cycles. Conventional screw connections cost time, pose a risk of leakage and put a strain on operating personnel.
The solution: WEH® quick connectors for evacuation. They enable tool-free connection in seconds – for smooth processes in gas logistics, refrigeration and air conditioning technology as well as in medical technology. Available for female and male threads, pin index, smooth tubes, with or without residual pressure valves – with different actuation variants for maximum ergonomics and safety. All WEH® products are manufactured from high-quality materials, undergo strict quality controls and offer reliable tightness.
