Abstract
A sight gauge is placed between two spaced apart compression type fittings connected to a vessel to show the liquid level in the vessel. The sight gauge has an elongated tubular transparent tube shield and a slightly longer elongated transparent sight tube that is received within the sight tube shield. An upper and a lower connection plate are each telescopically received by the sight tube, the sight tube shield being captured between the connection plates. An upper and a lower nozzle member each has an opening to respectively capture the upper and lower ends of the sight tube. An upper and lower elastomeric O-ring is received on the sight tube positioned between the connection plates and the nozzle members. Bolts secure the nozzle member to the compression plates to squeeze the O-rings against the sight tube so that the sight tube retains and supports the tube shield. Each nozzle member has an elongated tubular portion that can be received in a compression fitting.
