CAT OIL FILL CAP AND TUBE (1994-2010)

If you’re looking to replace a worn or leaking oil fill setup on your Caterpillar engine, the CAT Oil Fill Cap and Tube Assembly is a reliable replacement designed to restore proper sealing and easy oil access.

Over time, factory oil fill caps and tubes can wear out from heat, vibration, and constant engine movement, which may lead to oil leaks, loose caps, or difficulty when checking or adding oil. Replacing the oil fill cap and tube helps ensure a secure seal and proper fitment, keeping your engine bay cleaner and your oil system functioning the way it should.

This assembly is designed to work with a wide range of Caterpillar heavy-duty engines, providing a straightforward replacement that installs in the factory location.
