GeneralAluminum Construction
- Dual Dynamics pioneered the field with the grease hub cap, making the first and the best.
- Original design vents and resists contamination.
Mounting Gaskets
- Lightweight, strong, durable, non-corrosive and weather-resistant.
- Allows for rapid heat dissipation.
- Solid one-piece construction WILL NOT BREAK...
- Tamper-proof design eliminates costly mistakes of putting oil in grease wheel-end applications.
Patented Venting System
- Highly crush-resistant at high flange pressures.
- Gaskets have a FULLY CURED nitride binder which will withstand wheel-end temperatures up to 350 degrees.
Allows for two-way air movement while protecting the wheel end from outside contaminants. Designed to relieve wheel-end pressure and vacuum buildup. Provides excellent protection from water-filled loading docks and high-pressure sprayers. Patented cover protects sintered bronze vent from becoming contaminated with grease from inside the wheel end. Sintered bronze vent is nickel plated for exceptional corrosion resistance.
