The VAPCO PRODUCTS VPO-1 is a vacuum pump oil formulated for use in HVAC and refrigeration vacuum pumps. Vacuum pump oil serves as both a lubricant and a sealing medium inside the pump, allowing the unit to pull deep vacuums required for proper system evacuation. Sold in a 1-gallon container, this oil is the correct service fluid for maintaining pump performance and extending pump service life. Regular oil changes with the correct fluid are a standard part of vacuum pump maintenance on any refrigerant system job.
This oil is used during the evacuation phase of HVAC and refrigeration service work. Technicians use vacuum pumps prior to refrigerant charging on new installations, after component replacement, or any time the system has been opened to atmosphere. The 1-gallon size is practical for shop stock or field service vehicles where multiple pump oil changes may be needed across a service season.
Designed as a general-purpose vacuum pump oil for use in HVAC and refrigeration vacuum pumps. Consult your pump manufacturer specifications to confirm oil type compatibility before use.
Vacuum pump oil should be changed by a licensed HVAC technician following the pump manufacturer recommended service intervals, typically after each use or after pulling a system with high moisture content. Always disconnect the vacuum pump from power before draining and refilling oil. Dispose of used vacuum pump oil according to local regulations. Do not mix vacuum pump oil with refrigerant oils or other lubricants.
