Sight Glass: Tubular and Flat

We manufacture both tubular and flat sight glasses of borosilicate glass (pyrex) and quartz.
This includes heavy wall glass tubing for pressure / vacuum and lubrication applications, like oil sight glass or a boiler sight glass.

Many sizes and diameters of sight glasses are available with redline and heavy wall variations.

Both ends of the sight glass are ground square. Pipe sight glass with pipe flanges is also available.
