Efficient Testing, Safe Filling – WEH® Quick Connectors for Refrigeration and Air Conditioning Technology
Whether cooling systems, heat pumps, or air conditioning units – in refrigeration and air conditioning technology, maximum precision is essential when filling, evacuating, and testing. Manufacturers and service technicians are under pressure to meet stricter environmental regulations while working more efficiently – all amid increasing product variety and complex connection geometries.
WEH® Quick Connection solutions provide relief precisely where it’s needed: enabling pressure-tight connections in seconds on Schrader valves, straight tubes, threads, or bores – without screwing, without refrigerant loss. Ideal for use in manufacturing, service, and development. From refrigerant filling to leak testing, WEH® delivers proven solutions for refrigeration and air conditioning technology – ergonomic, cost-effective, and certified “Made in Germany.”
Common applications
Pressure and Leak Testing in Refrigeration and Air Conditioning Technology
Components must be reliably tested for leak-tightness – often under vacuum or compressed air. WEH® Connectors ensure instant connection and secure testing processes.
Refrigerant filling
Evacuating the refrigerant circuit
Before filling, cooling systems are evacuated to remove moisture and air. WEH® Connectors simplify this step with safe, time-saving handling – for maximum efficiency.
