Introducing the Monolith.
Our one-pierce design meets & exceeds new refinery standards.
Machined from a solid piece of acrylic.
To be clear, it's clear from the start.
Engineered for optimal visual oil analysis and inspection. Using an oil slight glass on your equipment can help to avoid a costly repair.
New design standard, same reliable oil sight glass.
The Monolith oil sight glass will be an early indicator of wear on the bearings, contamination problems and can help find the source of such problems. The oil sight glass alone will not prevent moisture from entering your reservoir or remove any water that has become emulsified in the oil. However, pump inspection regularly using oil sight glasses provides a visual inspection of the oil and a magnified view of the presence of sediment.
What customers say:
Randy Stewart, Pump Shop Supervisor
I work for a San Francisco Bay Area refining company. We use PK Machine Monolith oil sight glasses for their superior quality and clarity. We have used other brands but we threw them away because of the poor interior surface finish."
