Should I use copper anti-seize on both sets of threads?

 

Use the Permatex Anti Seize Lubricant in the 1 oz. tube or 8 oz. bottle - it comes out SILVER. The bottle looks like this and is the best value (http://www.permatex.com/products/Aut...ubricant_a.htm) while the one oz. tube looks like this (http://www.jegs.com/i/Permatex/775/8...oductId=752342)

This SILVER anti-seize lubricant is the industry standard and I've used it on car and motorcycle exhaust components for over 20 years. Works wonderfully.

 

If you already have the copper then use it, it will work just fine. If not then go with what rdondes suggested.

 

Thanks! Used silver.
