Viewports – 3D Plastic Lens

Viewports – 3D Plastic Lens

3D Viewports can be used to monitor oil levels within a sump housing and provide visual inspection of lubricant condition.

To resist corrosion, these viewports are offered in brass or zinc plated steel. The lenses can be removed in the field for cleaning, rather than purchasing and installing a new viewport. Extended lens design simplifies liquid viewing, especially on small sizes.
