Engineered to provide clear, real-time process visibility without disrupting flow, the SSG Series In-Line Sanitary Sight Glass is ideal for liquid cooling, chilled water and glycol systems, pharmaceutical and food processing, semiconductor facilities, HVAC, and other critical process applications. Available in 1/2″–6″ sizes with clamp, weld, flange, or threaded connections, the SSG Series features a full-bore design for near-zero pressure drop, borosilicate glass for thermal-shock and chemical resistance, and AISI 304 or 316L stainless steel wetted components for durability and corrosion resistance. Its high-precision polished finish and FDA-compliant EPDM sealing option support hygienic service, while optional 24V DC LED, rechargeable battery, and ATEX explosion-proof lighting provide clear visibility in low-light installations. Rated from full vacuum to 145 psi (10 bar) and temperatures from -4°F to 266°F (-20°C to 130°C), the SSG Series gives operators a simple, reliable way to visually monitor flow conditions while maintaining a clean, unrestricted flow path.
