Hand Oil Pump for Refrigeration & Air Conditioning Systems

This manual oil pump is specifically designed for charging refrigeration and air conditioning compressors with lubricating oil, even while the system is running. It is an essential tool for marine engineers and HVAC/R technicians who need to maintain cooling systems on vessels, in cold storage, or in commercial AC units. The pump allows for pressurized oil charging without system shutdown, preventing refrigerant loss and saving time.

Constructed with a durable stainless steel body and a transparent polycarbonate valve assembly, this pump is built to withstand the demanding marine environment. It features an automatic vent valve that equalizes pressure inside the oil drum, ensuring safe operation. The universal cone-shaped rubber adapter fits standard oil containers (1, 2.5, and 5-gallon), and the 1/4-inch SAE flare connection is compatible with common service valves. Each stroke delivers a precise volume of oil, allowing for accurate metering.

This hand oil pump is the reliable choice for routine compressor oil top-ups, reducing downtime and maintenance costs. Its reverse capability also enables oil extraction and recovery from the system, making it a versatile tool for any marine engineering toolbox.
