Product Overview

This CAT Oil Gauge Gasket is designed for use with the new threaded-style oil sight glass (also known as the bubble-style oil gauge) used in CAT Pumps crankcase covers. The gasket ensures a proper seal between the oil gauge and the crankcase cover, preventing leaks and maintaining system integrity.

This gasket is included with the updated CAT threaded oil sight glass and is compatible with CAT models 280, 290, 333, 430, and 10 Frame pumps, which have transitioned from the old pressed-in design to the newer threaded configuration.

✅ Note: For proper installation, the threaded oil gauge (PN 43987) and removal tool (PN 44050) may be required if replacing an old-style gauge.
