Oxygen sensor crush washers

[billbuilds]

     I'm swapping pipes out on my 2011 FLHRC and wondered if you guys see a need in replacing the crush washers on the oxygen sensors? This is at least the third set of pipes they'll be going in with around 60K on them. If so how do you get the old ones off? Thanks, Bill

I've used the same set of sensors (widebands) on dozens of sets of pipes- just use a good, O2 safe anti seize, and you should be fine.

Rigid ,
What would a good safe anti seize be....I was under assumption just use enough for the threads and do not get on sensor....what color is a safe one? Thanks...jimmy

Safe refers to catalytic convertor safe. Is this an issue? Are the sensors before or after the cat. Is there a cat? Use the cooper based stuff and you will be fine.

Some  anti seize can/will degrade the O2 sensors, so I look for those marked "O2 safe".
