Closed System Opto-Matic Constant Level Oiler w/Sight Gauge

Closed System Opto-Matic Constant Level Oiler with Sight Gauge

The Closed System Opto-Matic Oiler is designed for all types of equipment where a constant level in a oil housing must be maintained. The closed system design prevents contamination and spillage. The adjustable collar allows the oil level to be externally adjusted to the desired level. A 1/8 NPT port is provided for a vent line back to the housing to allow pressure balancing between the oiler and the housing.


Product Description

  • One piece glass reservoir ensures proper constant level function. Compared to competitive models, there is no possibility of air leakage that would cause overfilling of the housing.
  • Adjustable level setting allows use in many applications
  • Bottom of adjusting collar indicates actual oil level setting for easy set-up and maintenance
  • Side and bottom connections for simplified installation
  • Two inch sight gauge available for easy viewing of oil level

Color-code Closed System Opto-Matic Oilers to match lubricant dispensing containers, such as Spectrum Oil Containers, to avoid cross-contamination and misapplication of lubricant.
