SAE Sight Glass

SAE J514 sight glasses with straight thread O-ring boss. The window is bonded or fused into a housing forming a single-piece part requiring no maintenance during its lifetime. These sights make a hermetic seal with an O-ring fit in the groove between the port and the sight glass housing. The port is typically machined in using a porting tool conforming to SAE J1926-1. In other words, the sight glass boss follows the SAE J514 standard, while the port follows SAE J1926-1. Porting tools are available from a number of machine tool suppliers . These sights can be installed and uninstalled with the same O-ring several times without loosing the hermetic seal. Ideal for quick installations. SAE sights come in a variety of materials. Windows can be made from crystalline quartz, fused quartz, sapphire, borosilicate. For extended transmission range the windows are available in Zinc Selenide, ZnSe, for IR, or high-purity UV quartz. Metal housings are typically made from stainless steel.
