NPT-Threaded Sight Glass for H2S Service, NPT 1
Specifically designed for Hydrogen Sulfide, H2S service at high temperature, this sight window is an ideal choice for use in sour refinery process. The C-276 Hastelloy housing has a finish of 32 RMS providing smooth surfaces reducing residues or particle contaminants. A sapphire window is sealed into the housing with an all-metal seal. This sight glass has a long working life under severe temperature swings. The lifetime is unaffected by thermal or pressure cycling.Please note: The internal C-seal itself is rated to 27,700 psi pressure at 700 degrees C (1,292 F), this is the critical element of this sight window. Because the seal is made to the highest standards of quality with all critical features closely controlled, the manufacturing lead time of this sight window is long.
