Description
Vacuum pumps are full of moving parts that all need to stay exactly where they belong.
It measures exactly 23.2 mm across the inside and 1.18 mm thick. Made from tough spring steel that keeps its shape even after years of heat and vibration.
You’ll find it in the popular VC100 and VC150 rotary vane pumps. These are the reliable oil-lubricated models used in labs, small factories, medical equipment, and workshops everywhere.
Over time, rings can bend, break, or get lost when you’re doing maintenance. When that happens, you might hear rattling or notice the pump not running as smooth.
