The reservoir and sight are vented to allow liquid to reach the outlets by gravity.  Each feed has an adjustable precision needle valve to control the flow rate; friction locks guard against loosening from vibration. Drop feeding can be observed through the glass viewing window in the valve bodies. 

This reservoir design utilizes a permanent bond that eliminates gaskets.  The unit can be filled using the aluminum swing-away filler cap.  A Viton o-ring creates a seal between the reservoir and fitting.  The aluminum valves contain Buna-N seals (Viton and EPDM seals are also available).  Each valve features a 1/8" female NPT outlet.  There is a 5/8”-18 thread for mounting.  

This lubricator has 9 Feeds.  Anywhere from 2 to 24 valves may be connected to one reservoir.  The modular construction allows additional valves to be added at a later date if needed (part no. B3151-01B21GW).

The LED is powered by two button cell batteries installed at the factory.  The light activates for a few seconds each time motion is detected.  Replacement batteries are commonly available as part numbers SP357 or SR44W.  They may also be purchased from Oil-Rite as part number A7180-1.  The batteries are accessed by unscrewing the knurled cap from the lighting unit (no tools are required).  Use a magnet or rolled up tape to lift the two batteries out.  Insert the new batteries with the positive end down.  Hand tighten the knurled cap.

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.
