Sight glass widely used in all types of hermetic pump to observe the condition inside the container. Our sight glass is manufactured through high temperature sintering process. Thus, it has good air impermeability, high pressure withstanding capacity, and clear surface that ease the process of observation. Besides, we provide custom made service to our customer to manufacture sight glass that has extra high pressure withstanding ability with clear vision.
