Opto-Matic® Closed System oilier is designed for all types of equipment where a constant level in an oil sump must be maintained. Closed system design prevents contamination and spillage. Adjustable collar allows oil level to be externally adjusted to the desired level. A 1/8" NPT port supplies a vent line back to the housing to allow pressure balancing between oiler and housing. A 1-piece glass reservoir ensures proper constant level function. A 2" sight glass sight gauge is available for easy viewing of oil level.
