TSI Supercool V128 68 Synthetic Vacuum Pump Oil — 1 Gallon, Low-Volatility High-Oxidation Resistance

TSI Supercool V128 68 is a synthetic, low-volatility vacuum pump oil engineered to protect and extend the life of HVAC and automotive vacuum pumps.

Designed in the United States by SUPERCOOL, this V128 68 viscosity synthetic oil is formulated for broad compatibility with most vacuum pump brands. Its low volatility and high oxidation resistance help maintain consistent performance under typical service conditions, while the synthetic base improves thermal stability and reduces deposit formation compared with conventional mineral oils. The gallon size suits professional shops and serious DIYers who perform frequent maintenance on refrigeration, air conditioning, or automotive vacuum systems.

How does this oil improve vacuum pump reliability?

Using a synthetic oil like V128 68 helps keep internal pump surfaces cleaner and lubricated at elevated temperatures. Its high resistance to oxidation slows the breakdown process that creates sludge and acids, so seals and moving parts experience less wear over time.

• Low volatility minimizes vapor loss during high-temperature operation.
• Synthetic formulation resists thermal breakdown and deposit formation.
• Helps preserve seals and bearings by maintaining a stable lubricating film.

Is this oil compatible with my vacuum pump brand?

V128 68 is intended as a universal-fit vacuum pump oil suitable for a wide range of brands and models. Always check your pump manufacturer’s recommendations for viscosity and approved oil types before switching to a different formulation.

• Marked as universal fit for most vacuum pumps used in HVAC and automotive service.
• Matches typical VDL/ISO viscosity requirements for medium-viscosity pump oils.
• When in doubt, compare the recommended viscosity and service specs to V128 68.

What maintenance benefits can I expect with synthetic pump oil?

Synthetic vacuum pump oil typically extends service intervals by resisting contaminants and maintaining stable viscosity across temperature swings. That leads to fewer oil changes and lower risk of downtime due to degraded lubrication.

• Longer effective oil life reduces frequency of oil replacement.
• Cleaner internal components lower the need for pump tear-downs and deep cleaning.
• Consistent viscosity improves vacuum draw-down times and reliability.

How should I store and handle the one-gallon container?

Store the sealed gallon in a cool, dry place away from direct sunlight and ignition sources. When changing oil, warm the pump slightly for better drainage and follow safe disposal rules for used oil.

• Keep the container upright and tightly closed to prevent contamination.
• Use proper funnels and filtration when refilling to avoid introducing particulates.
• Dispose of used oil per local environmental regulations.

Who is this for: TSI Supercool V128 68 Viscosity Synthetic Vacuum Pump Oil in the one-gallon size is suited for HVAC technicians, automotive repair shops, fleet maintenance teams, and dedicated DIY enthusiasts who need a dependable, low-volatility oil for frequent vacuum pump service. It’s a practical choice if you require a U.S.-manufactured, synthetic pump oil that prioritizes oxidation resistance and cleaner pump internals without changing pump hardware or seals.
