Auburn Observation  
Auburn observation ports remain leak proof under high pressure and at high temperatures because of unitized one-piece construction.

Cico-weld eliminates the need for an organic gasket that can deterio­ rate under adverse pressure and temperature conditions. Pyrex viewing glass prevents cracking under rapidly changing operating temperatures.

Observation ports come in a wide range of viewing sizes and mounting threads for most standard OEM applications. Zinc plating is offered for application in corrosive environments
