Corning Pyrex® Brand ¾" Annular Edge Sight Glass

The Corning glass ring is specially designed for high pressure applications. The outer perimeter, raised on both sides, is polished to obtain a flat and parallel finish to the rest of the ring. When it is bolted to its position, the pressure is uniformly dispersed on the annular surface where the seal is placed, enabling it to seal effectively.

Available sizes : 4", 5", 6", 6 ¾", 8 3/8"
