ASME / ANSI B16.5 Flanged Sight Glass Windows- ASME (also know as ANSI) – Industrial, flanged sight glasses
- Exhibits no outgassing or contamination of most systems*
- Long working life
- No maintenance required
- Tested to high safety factor to insure safety & reliability
- Exceeds all industry and MIL standards
- Engineered, Manufactured and tested at the Rayotek U.S. facility
ASME (ANSI) flanged sight glass windows are engineered to endure harsh environments where extreme chemical, thermal, pressure and mechanical conditions are the norm. These flanged sight glasses are workhorses of the industrial world and Rayotek ASME flanged sight windows meet the challenge. The window is fused or bonded to a metal housing creating a hermetically sealed single-piece sight glass unit.
Our ASME flanged sight windows are designed for all B16.5 classes: 150, 300, 400, 600, 900, 1500 and 2500 psi. Custom higher pressures are available, please see Custom and exotic Sight Window page.
