Cylindrical Sight Glasses 25 mm To 150 mm

Sight glasses are the only components which are used in other than glass pipe lines. They are used for checking flow of liquids in the pipe lines. These are tubular site glasses and have full view of liquid flow from all directions.
Sight glasses are supplied with teflon bushes and teflon washers. The liquid contact parts are glass and teflon washers only. Hence, these sight glasses can be used in any type of pipe line.
Since the metal parts do not come in contact with liquid, sight glasses are generally made with M.S. body. However, S.S. bodies can be supplied on request. The flanges can be with drillings as per BS 10 table E or F, or as per ASA 150 ratings.
