The Leitenberger HAP 21 CMK Filling and Transfer Pump Master Kit is a superior quality, manually operated tool manufactured in Germany (Quality made in Germany), specifically designed for the precise transfer and handling of non-foaming and non-aggressive fluids such as compressor oils and brake fluids. This kit is the ideal choice for refrigeration, air conditioning, and general servicing tasks where excluding air and vapor from entering the system is critical.
The HAP 21 C pump is manually operated, thus requiring no external power source, ensuring flexible use in the most diverse working environments.
Key Application Example: Servicing of climate compressors
One of the main areas of application for the Master Kit is the servicing of air conditioning systems. The pump allows for the dispensing of compressor oil directly from the can into the crankcase of the refrigeration system's compressor. The biggest advantage of this method is that it is not necessary to evacuate the refrigeration circuit for the filling, and more importantly, it prevents the ingress of air and moisture into the refrigeration circuit, thereby ensuring system integrity and efficiency.
The Master Kit arrives in a robust black PVC carrying case containing all the necessary components for professional work:
| Part number | Component | Description |

Moisture and Air Exclusion: The special seals and the closed-system transfer process ensure that atmospheric air or vapor cannot enter the refrigeration circuit, which is critical for the lifespan and efficiency of climate control systems.
Oil Change Without Evacuation: Allows the compressor oil to be changed without having to place the entire system under vacuum, significantly reducing service time.
Versatility: The wide selection of included hoses and fittings ensures compatibility with various tank sizes and connections (SAE and BSP standards).
Portability and Durability: The light yet robust PVC bag makes transporting the tools to the site easy while protecting them from external damage.
This Master Kit is an indispensable tool for any professional who requires precise, reliable, and fast fluid handling in refrigeration and air conditioning technology.
