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 1/4” OD tube outlet. There is a 5/8”-18 thread for mounting. This lubricator has 10 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. B3151-01B11GW).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.
