Its high viscosity helps preserve sealing performance during demanding pulls while the thermally resistant base resists breakdown when temperatures climb. The clear, non‑detergent formula aids visual inspection through sight glasses and minimizes residue build‑up so technicians can complete clean, efficient evacuations.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this oil improve a vacuum pump’s evacuation performance?\u003c\/h3\u003e\n\n\u003cp\u003eUsing a purpose‑built, higher‑viscosity fluid helps the pump maintain tighter internal sealing and more consistent compression during deep evacuations.
