New and Improved and Environmentally Friendly.
Same Salt-Spray Resistance, Now Earth Safe!
Introduced back in 2001, TuffCoat™ plating set the "gold" standard in corrosion resistance.
Tested under SAE J516 and ASTMB117 salt-spray conditions, TuffCoat plating provided more than 400 hours of protection against the formation of red rust. That's a 500-plus percent improvement over the 72-hour SAE standard.
Today, TuffCoat plating is setting the "green" standard thanks to a new environmentally friendly manufacturing process. Due to environmental concerns, Gates has eliminated hexavalent chrome from the TuffCoat manufacturing process.
Hexavalent chromium, a material common in industrial plating, can be hazardous to the environment as illustrated in the movie "Erin Brockovich." The new TuffCoat manufacturing process does not affect coupling corrosion resistance or change torque recommendations.
As a running change, the new TuffCoat manufacturing process will affect all Gates manufactured couplings.
