Air compressor oil sight glasses are crucial components to allow you to check the oil level inside of an air compressor. Most air compressors will have an oil sight glass similar to the one in the image below that make it very easy to check the oil level inside the compressor. The compressor oil level sight glass window will contain a circular mark at the middle of which will help you depict the level as it has upper and lower limits.
