High-Pressure High-Temperature (HPHT) Sight Glass
Thread: NPT 1/2
All metal-sealed NPT sight glasses for simultaneous high pressure and high temperature applications. This is an optical access window engineered for operation in systems exceeding 6,000 PSI and 400 °C. It provides direct visual access into pressurized vessels, pipelines, and process equipment. The sight glass is comprised of a 316L stainless steel body, C-Axis Sapphire window and an Alloy 718 (Inconel) Ag-plated metal C-seal. The window is supported by a 316L cover on the side opposite from the pressure. The C-seal is directly between the main housing and the sapphire on the pressure side. There are no crevices trapping bacteria or creating virtual leaks. All wetted surfaces are open to purging. Materials of construction: 316L, sapphire and Inconel have excellent performance at cryogenic temperatures. The assembly is Helium gas-leak tight to 10xE-9 atm-cc/s2. Use traditional NPT installation methods with high-temperature thread sealant. Volume pricing is available. Hastelloy C-276 is available upon request.
