Cyclops Industries

Cyclops Industries, Inc. was established in 1959 and will be celebrating their 60th year in business in 2019. Cyclops Industries, Inc. is a designer and manufacturer of safety sight glasses, viewport assemblies, sight flow indicators, spray rings, sight lights and sight glass replacements for observing processes in industrial pressure vessels and pipelines. Cyclops sight glass provides maximum safety under high pressure, high temperature, corrosive and volatile processing operations. They can withstand a wide thermal shock range and are capable of resisting blow out or rupture. In most applications no packings, compression rings or screws are involved, eliminating costly continuous maintenance. With uncomplicated installation, safety sight glasses use only ASME approved materials and tolerances. During the late 40’s, early 50’s several localized plant explosions were experienced by a major chemical facility were directly attributed to the failure of conventional or sandwich type sight glasses. As a result, an engineer, Gene LeRoy was given the task of developing a sight glass that when broken, would maintain its integrity and not rupture or blow out, even while under extreme pressure at high temperature. After much trial and error, he hit upon the idea of peripherally sealing the lens assembly instead of vertically clamping and sealing the sight glass against the top and bottom lens gaskets.
