It could cause a failure. The line could be collapsing, causing no flow through it. This would cause a fail code.
No. It is "rubber" or a synthetic form of it. That is why it is called a rubber eraser and not a steel eraser.
Rubber.
No, rubber is more elastic than steel. Rubber has a high elasticity and is able to return to its original shape after being stretched or compressed, while steel has a lower elasticity and is more likely to deform permanently when stretched.
Rubber cannot cut steel, however the formation of carbon based cutting agents through exposure to ingress over time between the mating surface of rubber and steel will create a wear pattern and the illusion that the rubber has actually cut steel.
You will have to consult the manufacturer. A cast iron or steel globe valve could be trimmed (disc and seat) with bronze, iron, steel, stainless steel stellite, ceramic, rubber, neoprene, viton....or any series of different trims. The manufacturer usually determines trims by code numbers. Kinka valves indicates that this trim material on their valves is 304 stainless steel (13% chromium, and nickel content).

Steel has the biggest lumps on its surface compared to ice and rubber. This is because steel is a solid material with a rough and uneven surface, while ice and rubber are usually smoother and more uniform in texture.
Rubber, with steel belts, and plies made of a combination of rubber and or polyester, or nylon.
HDPE pipe can use a rubber ring, if the rubber ring is properly sealed with a steel gasket. The rubber ring must be placed in a groove in the pipe and then the steel gasket is placed on top of it.
