ABSTRACT:
An improved sight glass for use in determining the level of water in steam boilers and similar installations is disclosed. The end flanges are provided with molded inserts, preferably of PTFE or similar fluorocarbon material which serves to provide a sealing washer when the device is connected to communicating pipe flanges at an outer surface thereof, and provides a seal at the annular end surfaces of the sight glass. A concentrically disposed guard tube is also maintained in sealed relation relative to the end flanges, and is preferably of polycarbonate or similar material. The guard tube is supported by oppositely disposed rectangular cross-sectioned "O" rings which provide for the sealing of the cylindrically shaped space between the outer surface of the sight glass and the inner surface of the guard tube. Peripherally positioned tie rods prevent excess tightening of the end flanges, thus preventing excess axially oriented pressure on the sight glass.
