eagle Posted January 29, 2009 Report Share Posted January 29, 2009 I was curious if anyone knows what the higher temp o-rings in the coolheads are made from? The ones around the domes. We are O-ringing a race kart head and need to select the right compound. Anyone? I am leaning towards Viton but not real sure at this point.

You can always go with Kalrez O-rings :biggrin: :biggrin: Bet you will not like the price though. We have some applications using Viton with good results. There are better choices though.

jayzx10r Posted January 30, 2009 Report Share Posted January 30, 2009 I've seen sets that have a couple of red rings, the other manufacturer includes only black rings. Is one set preferred over the other?? Does it matter?? Jay. Quote Link to comment Share on other sites More sharing options...

Brandon Viton is what you need for the fire face of the domes unless you are weirdo like a few of us and cut the domes to use copper wire rings. EPDM will work for the rest of the o-rings in the head. Quote Link to comment Share on other sites More sharing options...

You can get Viton or it's non-proprietary (bonus points to someone who knows the company who owns the rights to Viton) counterpart in black, brown, grey, orange, red, and fruity blue color. :cool: Quote Link to comment Share on other sites More sharing options...

FireHead Posted February 1, 2009 Report Share Posted February 1, 2009 What is Dupont? That might be right. It's either them or Dow. I can't remember off of the top of my head (hence the bonus points offer). :biggrin: Quote Link to comment Share on other sites More sharing options...
