Our SP4000 observation window, also known as a sight glass or view port, is much larger than other observation windows available on the market. It’s large size allows the user to shine a light and look through the window simultaneously, which is not possible with smaller sizes. It is provided with o-rings and a mounting nut for a hermetic seal.
