Abstract

An improved fluid level verification apparatus which may be manufactured or otherwise fabricated as a kit and assembled at a remote location for use on liquid filled containers and configured to reduce inherent mechanical stresses on the inspection tube and resists leakage due to environmental, chemical, thermal, or mechanical expansion cycles using internal grooves and entrapped o-rings sheathed into multi-faced end blocks in a symmetrical configuration.
