# Leitenberger HAP 21 CMK Filling and Transfer Pump Master Kit<\/p>\n
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.<\/p>\n
## Main Features and Application Areas<\/p>\n
The HAP 21 C pump is manually operated, thus requiring no external power source, ensuring flexible use in the most diverse working environments.<\/p>\n
**Highlighted Application Example: Servicing an Air Conditioning Compressor**<\/p>\n
One of the main application areas of the Master Kit is the servicing of air conditioning systems. The pump enables the injection of compressor oil from the can directly 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 refilling, and more importantly, **it prevents the ingress of air and moisture** into the refrigeration circuit, thereby ensuring the system's integrity and efficiency.<\/p>\n

## Advantages of the HAP 21 C Pump<\/p>\n
1. **Exclusion of Moisture and Air:** The special seals and the closed-system transfer process ensure that atmospheric air or vapor does not enter the refrigeration circuit, which is critical for the lifespan and efficiency of climate control systems.
\n2. **Oil Change Without Evacuation:** Enables the replacement of compressor oil without having to place the entire system under vacuum, significantly reducing service time.
\n3. **Versatility:** The wide selection of included fittings and hoses ensures compatibility with various tank sizes and connectors (SAE and BSP standards).
\n4. **Portability and Durability:** The lightweight yet robust PVC bag facilitates transporting the tools to the site while protecting them from external damage.<\/p>\n
