Brass Liquid Level Gages are used to indicate level of lubricating oil supply at bearings, gear boxes, crank cases, transformer, switches, etc. Compact Design can be installed easily in any location having enough clearance for a one-piece oil gage. Gages can be disassembled for installation in very tight places. Square shank, with pipe thread, screws horizontally or vertically into tapped hole. Options are available for difficult or irregular mountings. Quality built shank body, cylindrical brass shield and cap are machined to close tolerances. Sights are clear, sturdy gage glass. For a leak tight seal, a Buna-N seal and a polypropylene glass protector are furnished. Other commercial seal materials are available on request. Modifications available if desired, these elbow liquid level gages can be supplied with High or Low labels or level marks. In addition to the standard line, many special gages, similar to the ones described here, have been developed for customer's specific applications. Should you have special requirements, our engineering service is available without obligation.

Flush Mounting Liquid Level Gages are an extensive line of gages visibly indicating liquid levels
and mount flush against the outside surface of liquid storage vessels. The gages are
compact in size, with a minimum amount of protrusion. Large liquid passages effect a quick
level response. Liquid level gages for flush mounting are used for a multitude of applications
such as tanks, reservoirs, packaged hydraulic equipment, steel mill pumps, hydraulic presses
and for any other application where it is desirable to indicate liquid levels. The liquid
reaches the sight through the lower hollow mounting bolt, while displaced air vents back into
the reservoir through the upper hollow mounting bolt. Flush Channel Level Gage Back Mounting Model No.

BSPT Milled Aluminum Liquid Level Gage. Oil-Rite Corporation?
is pleased to announce its new line of Aluminum Liquid Level Gages. These new gages offer a rugged
milled aluminum construction with a unique staked end body design to handle any industrial liquid
level application. These new gages can be used to view liquid levels in hydraulic reservoirs,
gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs. Fluid enters through
a cross hole in the hollow lower bolt and is communicated back into the tank, through the cross hole
in the hollow top bolt. The gage is offered in centerline lengths ranging from 3" to 36". The
unique design of this gage minimizes parts and optimizes production capabilities thus offering a
very competitive liquid level gage. The milled aluminum components resist rust and corrosion.

Window Sights are principally used to indicate a liquid level but can also show fluid in motion and mechanical movements under pressure. Two or more sights can indicate a high or low level, and if desired, levels in between. An exclusive feature of the fused and gasketed window sights is the new stainless steel reflector for maximum visibility in poor light. For clarity and with no loss in quality, the gasketed window sight surpasses other units in the field.
