Saf-T-Eye® Port Angular Model Number 12

Saf-T-Eye® Observation Ports The Saf-T-Eye® observations ports, when placed in a suitable position on the furnace, oven, or boiler wall, enable the operator to safely and clearly inspect the interior. Adjustments can be made under actual operating conditions without air infiltration or flame sting-out. Three types of glass are available for a variety of viewing options, such as borosilicate, cobalt blue, and quartz glass. The glass is protected by a stainless steel screen and shutter, which closes automatically when the handle is released. Wing nuts allow the glass to be easily removed for cleaning or replacement. Each unit includes a 1/4″ NPT purge hole for adding cooling capabilities with air or nitrogen. Sealant can be added to improve the seal in pressure applications. All Saf-T-Eye® observation ports are provided with a mounting flange gasket that fits securely between the unit and the vessel wall. All configurations of the Saf-T-Eye® observation ports are available in cast iron (except for the model 16, which is carbon steel) from stock. Fabrication in other metals for specific applications is available upon request. Optional Features: – Fabrication in other materials such as carbon or stainless steel. – Machine modifications to suit specific requirements. – Addition of high-temperature sealant to enhance pressure-seal. – Increase size of purge hole to allow more air flow. – Adapt shutter with special pattern of holes to increase cooling.
