Nu-calgon NUCAL-4814-40 Refrigeration Oil Charging Pump

Product Description

The NU-CALGON NUCAL-4814-40 is a hand-operated refrigeration oil charging pump designed for adding or removing refrigeration oil during service on air conditioning and refrigeration systems. Delivering 2.6 fluid ounces (78 ml) per stroke against up to 200 psi of system pressure, it allows technicians to charge or recover oil while the system remains fully operational. No shutdown is required, reducing system downtime during routine oil service. A fitting and transfer hose are included, and the pump is compatible with all refrigeration oil types.

This pump is used by licensed HVAC and refrigeration technicians servicing residential and commercial air conditioning and refrigeration equipment. It is compatible with one-gallon, two-and-a-half-gallon, and five-gallon oil containers, making it practical for both field service vans and shop environments. The ability to operate under live system pressure makes it especially useful in commercial refrigeration applications where system downtime is costly.
