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, 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 window sight may be mounted into any corresponding pipe thread. It withstands up to 50 PSI and 225° F.","304 Stainless steel is known for its non-corrosive and non-magnetic properties. Because it is resistant to corrosion, rust, and staining, it maintains its appearance over long periods and minimizes unwanted bonding between parts. The body of this window sight is constructed with 304 stainless steel. The glass viewing sight is secured by a 304 stainless steel retaining ring. A Buna-N o-ring creates a leak tight seal. A nylon washer is seated between the retaining ring and sight to prevent glass abrasion. A stainless steel reflector maximizes liquid level visibility, even in poor light. The reflector will not tarnish, corrode or discolor under the most adverse of conditions.","This unit features a 1 1\/2 male NPT mounting thread. It has a 2 hex and 1 17\/32 sight diameter. When tightly secured, it extends about 17\/32 from the mounting surface.
