o-rings
 

would like a price on o-rings for a 12v head(not fire rings)

Hello vendors

its ok wild bill aparently nobody wanted my buisness so i took it somewere else

Well you can't just buy O-Rings... Its not like a bolt on. You have to have the head machined, most vendors aren't machine shops. And you wouldn't want to ship a head to a vendor to have it machined, the shipping would cost more than the mill work. The O-Rings themselves are just stainless steel wire thats pressed into the groove.
