Economical Hermetic Sealing of Rayotek Threaded Sight Glasses



The function of Rayotek NPT and SAE threaded Sight Glasses are to provide visual accessibility for observation of closed and sealed systems. The proprietary technologies for economically sealing optical materials to metal make Rayotek's high pressure and ultra-high pressure windows both reliable and affordable.



San Diego, CA - The function of Rayotek NPT and SAE threaded Sight Glasses are to provide visual accessibility for observation of closed and sealed systems. Rayotek NPT and SAE Sight Glass Windows utilize materials such as glass, fused silica, fused quartz, sapphire and other clear materials sealed into a corrosion resistant metal housing to form a hermetically sealed and durable product.



A huge advantage of Rayotek's NPT and SAE Threaded Sight Glasses is that maintenance is not required, routine cleaning is all that is needed.



BILL RAGGIO, PRESIDENT AND CTO



Rayotek NPT and SAE Sight Glasses are used in a multitude of industries.  They can be found in the petroleum, natural gas, pulp and paper mill, marine, deep sea, aerospace and medical sectors. They are used for visual accessibility in a variety of locations, such as: 



high pressure tanks

hydraulics

flame and explosion chambers

furnaces

hazardous systems

supercritical systems

sanitary, pharmaceutical and food processing systems

ultra-high pressure and vacuum systems.



Providing a robust, long lasting hermetic seal is critical to a Sight Window performance. Rayotek has several proprietary technologies for economically sealing optical materials to metal. These methods make Rayotek's high pressure and ultra-high pressure windows both reliable and affordable.



Manufactured to ISO 9001:2008 standards, Rayotek's NPT and SAE Sight Glasses are particularly resilient in extreme thermal, mechanical, chemical and pressure settings.  In addition, they are engineered, manufactured and tested at Rayotek's U.S. facility.



"A huge advantage of Rayotek's NPT and SAE Threaded Sight Glasses is that maintenance is not required, routine cleaning is all that is needed.  They have a long working life, and with most systems they exhibit no outgassing or contamination."  says Bill Raggio, Rayotek President and CTO.  "In addition, they are able to operate in high purity, ultra-high vacuum, clean room rated systems, adding virtually no contaminants to systems."
