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

When to Change Your Vacuum Pump Oil
JOHNSEN'S recommends changing your vacuum pump oil every 6 months or after heavy use. Dark, milky, or contaminated oil reduces your pump's ability to achieve deep vacuum and can cause internal damage over time. Regular oil changes are the single most important maintenance step for any HVAC vacuum pump.
