Oil sight glass, by PK Machine.

Instant Visual Oil Inspection

Since 1962

Designed and engineered for optimal visual oil monitoring, our oil sight glass reveals oil contamination, sediment, discoloration and water contaminant levels.
Also known as a water finder or Deb jugs, water is just one element that can cause damage and premature wear. Visual oil condition monitoring provides an immediate insight into the condition of your oil.

Oil condition monitoring provides all plant personnel the insight to spot problems long before it becomes a costly repair.
