Sanitary Wafer-Type Sight Glass
The Wafer-Type Sight Glass (also known as a sandwich sight glass) is a slim, face-to-face design that is clamped directly between two pipeline flanges using through-bolts. It provides a space-saving, zero-dead-leg inline viewing solution suitable for hygienic applications. The compact body reduces installation length and minimises hold-up volume compared to conventional flanged sight glasses.
