Oil-Rite B4764-01V 观察窗

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 a tapped hole or used with the stainless steel mounting nut for a drilled hole. A Viton 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 9\/64. It withstands up to 125 PSI and 300° 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 Viton 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\/2-20 mounting thread and stainless steel mounting nut. It has an 11\/16 hex and 5\/16 sight diameter. When tightly secured, it extends about 3\/8 from the mounting surface.","*The image on this page is for illustrative purposes only and not representative of the actual size of this item.
