The phrase "against vacuum" is not correct and does not convey a clear meaning in written English.
It may be intended to describe a situation or action that opposes or counters a vacuum, but the expression lacks clarity and context.
Example: "The design of the container is meant to work against vacuum pressure to ensure its integrity."
Alternatives: "in opposition to vacuum" or "counter to vacuum".

But these bearings wear down over time and must be sealed carefully against vacuum and other things that might damage them.
Within the EUROfusion Programme the permeation against vacuum (PAV) technique has been considered as baseline for those blankets which use PbLi as breeder.
The Permeator Against Vacuum (PAV) has been conceived as the simplest, cost effective and reliable technology system dedicated to tritium extraction from breeding liquid metals.
The Permeator Against Vacuum (PAV) is one of the candidate Tritium extraction and removal technology from the Lithium-Lead circulating in the breeding blanket currently under consideration for the EU DEMO.
Permeator against vacuum (PAV) runs as a single-step process for tritium on-line recovery, acts as passive systems allowing to be thermally governed can be easily in-pipe integrated in LiPb loop systems and can be conceived with high compactness.
Dyson is taking legal action against rival vacuum makers Bosch and Siemens, over behaviour that it says is akin to the Volkswagen emissions scandal.
The hydrostatic pressure on the ocean bottom, however, exerts an upward pressure on the core that will work against a vacuum being created between the piston and the top of the core.
Located back from the seacoast above high, deep-red cliffs, the town faces away from the sea but is connected to it by a pedestrian right of way and by a remarkable railway originally designed to demonstrate a system of propulsion by atmospheric pressure against a vacuum devised by Isambard Kingdom Brunel.
