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

  • Quick and easy connection in just a few seconds
  • No tedious hand tightening
  • Various actuation options
  • For maximum ergonomics and safety
  • Saves time and money & boosts productivity
  • Protection of operators’ joints

Your Benefits

Time-saving handling

Tool-free connection in seconds – ideal for frequent or time-critical processes.

Leakage-free evacuation

Reliable sealing for clean, efficient evacuation processes.

Safe working

Integrated safety functions such as locking, protective bracket or pressure relief increase operational safety.
