JOHNSEN'S Vacuum Pump Oil – 32 oz. | HVAC & Refrigeration

HVAC Vacuum Pump Oil – 32 oz. | For Deep Vacuum Evacuation JOHNSEN'S 32 oz. Vacuum Pump Oil is specially formulated for HVAC technicians and refrigeration professionals who need reliable, deep vacuum performance. Whether you're evacuating an R-410A, R-22, or R-134a system, using the correct vacuum pump oil is essential for achieving micron-level vacuum depth, protecting your pump, and ensuring a moisture-free system charge. Why Use Dedicated HVAC Vacuum Pump Oil? Standard oils break down under the extreme low-pressure conditions inside a vacuum pump. JOHNSEN'S vacuum pump oil is engineered to maintain viscosity, absorb system moisture and vapors, and provide consistent internal sealing — so your pump pulls deeper and lasts longer. Recommended for use with single-stage and two-stage rotary vane vacuum pumps. Key Benefits Deep Vacuum Performance – Promotes internal sealing for consistent micron-level evacuation on HVAC and refrigeration systems Cold Start Formula – Engineered for reliable cold-weather startup without viscosity breakdown High-Temp Stability – Maintains maximum viscosity at elevated running temperatures for continuous lubrication and protection Vapor Absorption – Absorbs moisture and unwanted vapors from evacuated systems for cleaner operation Extended Pump Life – Reduces internal wear for maximum pump longevity and performance Broad Compatibility – Compatible with most single-stage and two-stage rotary vane vacuum pumps used in HVAC and refrigeration Specifications Brand JOHNSEN'S Size 32 oz.
