TSI Supercool Vacuum Pump Oil, Synthetic, 32 Oz., Clear (V32)

It's nice and clean and got the vacuum pump pumping smooth. Sounds brand new and pulled a tight seal quickly. The dirty oil could pull 29 bars negative pressure, and with the new oil is off the gauge at 31 bars.

My vacuum hesitated going to 30 now. It goes well past -30 no blow by.

This is good oil. I used a cheaper brand available at an import tool store. You know the chain that always give 20% discount. I couldn't get a system down to 600 micron no matter what I tried. Got this oil, used the same setup, went down to 400 micron in quick order. Good quality vac oil is worth it, oh and change the oil frequently.

The vacuum pump oil works as described. It was used for a few vacuum and recharge projects and wirked as intended. Not much of a scent and seemed similar in consistency of more expensive brands.

Good product

We make custom soft plastic fishing lures (YATES BAITS) and purchased one of the cheapest vacuum chambers on Amazon because we knew that the pump probably wouldn’t last due to degassing hot plastisol and eventually have to buy several new pumps throughout the lifetime of this business. We bought this oil with the pump merely based on reviews and never used the cheap mineral oil looking stuff that came with the pump. After changing the first break in period to inspect for metal shavings and debris, this pump has been abused for years now (as you can tell from the color from the oil, thats not internal wear but plastisol colorant that has been sucked into the motor and mixed with the oil). No gasket or seal leaks, no damage to the diaphragm.. Nothing. Maybe the tolerances are better now in pumps than what they used to be but I’m still a believer in this oil. Short run cycles throughout the day and it doesn’t get hot or loud, this isn’t a paid testimony.. just wanted to share our experience with this oil and maybe help someone out.

Very good product!

The go to standard for freeze dryer pumps.
