TuffCoat™ & TuffCoat Xtreme® Coupling Plating


New, Improved, and Environmentally Friendly Coupling Plating

Unsurpassed Salt-Spray Resistance That's Earth Safe!

Introduced back in 2001, standard TuffCoat™ plating set the "gold" standard in corrosion resistance.

Tested under SAE J516 and ASTMB117 salt-spray conditions, standard TuffCoat plating provided more than 500 hours of protection against the formation of red rust. That's over 340% longer than the new 144-hour SAE industry standard. 

And now new TuffCoat Xtreme® plating raises the bar to over 840 hours of red rust protection under the same salt-spray conditions.  This is over 580% longer than the new 144-hour SAE industry standard.

TuffCoat plating is also "green" thanks to an environmentally friendly manufacturing process. Due to environmental concerns, Gates eliminated hexavalent chromium 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."

Get unsurpassed protection against rust and corrosion with TuffCoat and TuffCoat Xtreme plating.
