New, Improved and Now 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.
