Color Key Clear View Single Feed Manual Lubricators are ideal for continuous operation. Liquid is dispensed when the lubricator is turned on with a toggle shutoff (using the toggle does not affect the metering adjustment).  This oiler features an acrylic reservoir. The lightweight and durable endplates are made from green polypropylene. The item is also available in red, blue and yellow. Maximum fluid visibility is achieved by eliminating the center post common to many reservoirs.

The reservoir and sight are vented to allow liquid to reach the outlet by gravity. An adjustable precision needle valve controls the flow rate; it has a friction lock to guard against loosening from vibration. Drop feeding can be observed through the glass viewing window in the valve body.

This reservoir design utilizes a permanent bond that eliminates gaskets.  The unit can be filled using the aluminum swing-away filler cap.  The aluminum valve contains Buna-N seals (Viton and EPDM seals are also available).  A Viton o-ring creates a seal between the reservoir and fitting.  This lubricator is pipe mounted using a plated steel fitting with a 1/2” male NPT thread.

Some of the advantages of Color Key products are:

Identification of Fluid Type
Plants that use a range of fluids (different oil weights, mineral spirits, etc.) can utilize a color coding system to ensure that each reservoir is replenished with the appropriate fluid.

Highlight a Monitored Point
Fluid levels need monitoring, but can be easily overlooked as just another part of a much larger and complex piece of machinery.  A colored reservoir can stand out from the surrounding components and draw the attention of operators and maintenance individuals.

Frequency of Maintenance Checks
Fluids may be consumed at different rates and may require more or less frequent inspection.  Color coding a reservoir can serve as a simple method for prioritizing or scheduling inspections. 

Colored reservoirs can be coordinated with colors on the original equipment, accentuate the equipment’s brand, or complement the factory’s logo and color scheme.

The diameter of the reservoir is 5 1/2” and the total height of the lubricator is 11 5/8”. It is suitable for temperatures up to 160° F.

NOTE: This reservoir is not for use with isopropyl alcohol.  Polycarbonate reservoirs or reservoirs with aluminum endplates and Viton seals are recommended for use with isopropyl alcohol.
