Fixture for pressure testing sight glasses

摘要

A fixture for pressure testing sight glasses includes a base having a recessed pressure chamber therein, a peripheral seal ring in the pressure chamber and a supply passage for supplying a pressurized fluid to the pressure chamber. The test fixture is operable by securing a sight glass on the fixture so that the sight glass is received in sealing engagement with the seal ring above the pressure chamber in order to apply a predetermined fluid pressure to the sight glass.
