Stainless Steel Gasketed Window Sights allow visual observation of liquid levels and their condition. They can be used to display fluid motion or mechanical movements, as well as to view and perform tests in a safe enclosure. Specific uses include fluid sighting on hydraulic tanks, pressure vessels, reservoirs, packaged power equipment, machine compartments, hydraulic lines and dipping. Their use can be applied to any application where oil or fluid inspection is essential. Two or more sights can be mounted so as to indicate high, low or in-between levels.
This straight threaded window sight may be screwed into any corresponding tapped hole. This item is also available with a nut for use with a drilled hole (window sight #B4764-05B). A Buna gasket is provided to fit between the window sight and tank, preventing leakage past the threads. This window sight can be used with a maximum wall thickness of 1/4”. It withstands up to 100 PSI and 225° F.
Stainless steel is resistant to corrosion, rust, and staining. It maintains its appearance over long periods and minimizes unwanted bonding between parts. The body of the window sight is constructed with 303 stainless steel. The glass viewing sight is secured by a 303 stainless steel retaining ring. A nylon washer is seated between the retaining ring and sight to prevent glass abrasion. A Buna-N o-ring creates a leak tight seal between the body and sight. This window sight is also available with a stainless steel reflector to enhance liquid visibility.
This unit features a 1 1/4"-12 mounting thread. It has a 1 1/2” hex and 1” sight diameter. When tightly secured, it extends about 15/32” from the mounting surface.
