Oil sight glasses reveal lubricant condition
Lubrication Engineers is an authorized distributor of high-quality, affordable Xtract™ sight glasses. These easy-to-install sight glasses take the guesswork out of fluid lubrication management. The Xtract sight glass product line enables continuous visual monitoring of the clarity, color, sediment and water contamination levels of your lubricants. Some models even allow you to easily remove the water by draining it right out of the system. The variety of sight glass solutions available will help advance your lubrication reliability program to the next level.
Xtract™ Sight Glasses at a Glance
Xtract Oil Sight Glass
Xtract™ Oil Sight Glass is suitable for most applications. Installed vertically or horizontally, it enables an immediate visual inspection of the oil. More importantly, this sight glass allows for the draining of any accumulated water, using the spring-loaded drain valve. The OSG can be installed directly to a drain port located at the bottom of a reservoir or with an elbow for drain ports located at the side of the equipment. The Xtract OSG is constructed of brass hardware (stainless steel optional) and a high performance polyamide bottle, capable of withstanding the pressure and temperature of most operating environments.
Xtract High Temperature Oil Sight Glass
Heavy-walled Pyrex glass and Teflon end caps make the Xtract™ High Temperature Oil Sight Glass suitable for use when the radiant heat from nearby equipment exceeds the temperatures that allow safe use of LE’s Xtract or other Xtract oil sight glass products. These are only available in a vertical style and can withstand temperatures up to 450 degrees Fahrenheit (232 degrees Celcius).
Xtract Large Volume Oil Sight Glass
Perfect when high water volume accumulation is a problem, the Xtract™ Large Volume Oil Sight Glass provides the extra storage necessary to hold a large amount of water until it can be drained between maintenance checks. It is used on equipment that requires regular high-pressure washdowns or has high condensation problems, where water contamination cannot be avoided or minimized.
Xtract Oil Sight Glass & Level Monitor
The columnar style Xtract™ Oil Sight Glass & Level Monitor is the all-in-one solution, allowing operators to manage oil levels, visually inspect lubricant condition, and easily drain off any water. Red and green decals are included with the OSGL to mark upper and lower limits, or to designate running oil level and idle oil level. This clear acrylic vertical oil sight glass provides a highly visible 360-degree view of the oil and can be hooked up to a desiccant breather, making it a substantial upgrade from an old vented brass-and-glass sight gauge.
The dual port model has a second 3/8″ NPT thread at 180 to allow the installation of a drain valve or access to the oil reservoir utilizing a pitot tube and a pitot sample adaptor.

Xtract 3-D BullsEye Sight Glass
Used in conjunction with a standard OSG or alone on equipment where there is no water problem, the Xtract™ 3-D BullsEye™ Sight Glass window is another Xtract tool that provides easy visual monitoring of oil.
Unless you are standing directly in front of them, old-fashioned sight plugs on oil reservoirs make it difficult to view the oil level. The glass stains easily and is partially obscured by the hardware around it. LE’s solution is the 3-D BullsEye Sight Glass. This one-piece cylinder, made of a high-performance transparent polyamide, allows immediate and accurate visual oil level monitoring from virtually any angle. Engineered to outperform and outlast traditional view ports, the inherently strong material provides excellent impact, chemical and UV resistance.
Xtract Oil Level Indicator
LE’s columnar style Xtract™ Oil Level Indicator is recommended for monitoring the oil level inside large tanks, gearboxes or reservoirs when water contamination is not a problem. An old-style vented oil gauge made of brass and breakable glass can be replaced with an OLI (right), which is constructed of strong clear acrylic and provides a 360-degree view of the lubricant. In addition, you can attach a desiccant breather to the oil level indicator, an option not possible with the old style gauge.
The Xtract Oil Level Indicator can be used alone when there is no water problem or installed on equipment that also has a standard OSG. The sight glass allows the operator to visually inspect the condition of the oil and to take appropriate preventive action such as draining the water. The OLI is needed because the sight glass is situated too low to properly indicate oil level in this scenario.
