Cat® Fluids were specifically designed for Caterpillar machines and provide longer engine life and performance. They were created and tested by specialists under extreme conditions and applications. STET and Caterpillar offer a variety of Greases, Coolants and Oils for specific applications and components.

Don't put your investment at risk by using other brands of fluids. Although they may meet industry standards, only Caterpillar has the in-depth knowledge to design fluids that deliver maximum performance within Cat® Machines and Engines. And since they are developed, tested and approved according to the Caterpillar's exacting standards, our customers can safely use their entire fleet. 

The use of quality fluids is a key element for the health of your equipment.

STET and Caterpillar offer the right coolant to meet the needs of your machine or fleet. Extended Life Coolants, as well as conventional coolant/antifreeze, are included in our product line.
To help extend the life of the coolant, we also have a wide range of additives that allow you to extend the replacement intervals, saving you time and money.
Test kits and tools help prevent machine downtime because of the early change interval and provide early detection of problems, preventing serious damage to the component.
After finding brands in the market that no longer offered sufficient protection, Caterpillar developed its own grease, ensuring superior protection for the planet's most adverse environments.
Cat® Grease was designed specifically for Cat® Machines in order to reduce many wear problems, such as irritation and abrasion, and to help prevent gripping. It is also corrosion resistant and can be washed with water or salt water.
