TriboDyn TRI-EX² Ceramic Extreme Pressure Grease
TriboDyn TRI-EX² Extreme Temperature & Extreme Pressure Grease is engineered to protect critical components in the harshest operating conditions. Its patented Ceramic Charged® technology actively forms a durable protective film under extreme heat and heavy loads, where conventional greases can fail.
This high-performance grease delivers reliable lubrication across a wide temperature range while providing excellent resistance to water washout, corrosion, and mechanical breakdown.
Key Benefits:
- Patented ceramic technology forms a self-lubricating film under extreme pressure and heat
- Excellent protection in high-temperature and high-load applications
- Strong resistance to water washout and corrosion
- Helps reduce friction and wear on bearings, gears, and sliding surfaces
- Maintains consistency and performance under severe operating conditions
- Long-lasting protection that reduces relubrication frequency
Recommended Applications: Ideal for automotive, industrial, agricultural, and heavy equipment applications where extreme temperature and extreme pressure performance is required. Suitable for wheel bearings, chassis points, fifth wheels, pins, bushings, and other high-load components exposed to heat, moisture, or heavy shock loads.

Why TriboDyn Moly-5 Outperforms Ordinary Grease
Extreme Pressure & Film Strength
Typical greases fail at around 400 kgf on the Four Ball EP Weld Load test. Tri-Ex² delivers 800+ kgf — twice the load-carrying capacity of ordinary grease. This means unmatched protection against shock loads and heavy pressure in the most extreme applications.
Patented Ceramic Coating
Only Tri-Ex² contains the highest level of patented ceramic coating technology. Under extreme heat and pressure it forms a durable self-lubricating ceramic film that actively protects metal surfaces, fills minor wear areas, and dramatically reduces friction where standard greases cannot.
Extreme High-Temperature Stability
Most greases soften or melt under extreme heat. Tri-Ex² maintains structure with a dropping point of 580°F minimum and continuous use up to 650°F — delivering reliable protection in the hottest, most demanding applications.
Extended Equipment Life & Less Downtime
The highest moly content combined with the highest level of patented ceramic coating gives Tri-Ex² unmatched wear protection, adhesion, and longevity — reducing maintenance frequency and keeping equipment running longer in the toughest conditions.

Frequently Asked Questions
Tri-Ex² is our flagship grease with the highest level of patented ceramic coating and the highest moly content. It actively forms a durable self-lubricating ceramic film under extreme heat and pressure, providing unmatched protection where standard greases fail.
Tri-Ex² is engineered for the most severe conditions: extreme heat and extreme pressure applications such as pins, bushings, bearings, chassis points, fifth wheels, king pins, and heavy shock-load components in mining, construction, agricultural, and heavy industrial equipment.
Extremely well. It has a maximum 5% loss in the Water Wash-Out test and excellent water spray-off resistance, so it stays in place and continues protecting even when exposed to rain, mud, pressure washing, or heavy water spray.
Tri-Ex² performs reliably from -22°F to 650°F (-30°C to 343°C) in continuous use, with intermittent capability up to 750°F (399°C). Its high dropping point and patented ceramic technology ensure it maintains structure and lubricating power under the most extreme heat.
Yes. It meets or exceeds NLGI GC-LB specifications (the highest rating for automotive wheel bearing and chassis greases) and is specifically designed for extreme heat and extreme pressure applications.
Tri-Ex² is compatible with most other lithium complex and conventional greases, making it safe to top off or transition during regular maintenance. All TriboDyn greases are proudly formulated and manufactured in the United States in our own ISO 9001 certified facility.
