Yep, I did go there and that's why I asked because they say "If an ancillary product is to come into direct contact with a FlowGuard pipe & fittings system, BlazeMaster fire Sprinkler system and/or Corzan industrial system and is not included in the FBCT System Compatible Program, Lubrizol recommends that chemical compatibility be confirmed with that product's manufacturer prior to use." Direct contact being the key I think.
There doesn't appear to be incompatible cutting oils. Several tested ok. FM approval for pipe internally coated pipes so that seems like less of a problem. There are several sealants not compatible and a few that are compatible. All that is well a good except I can't see anything about indirect contamination. So if the existing system has known incompatibles or unknowns is that direct contact? If I drill on a saddle probably don't use any cutting oil. If I use the right thread sealant on the new work no problem. What if any oil is left from the original installation, probably not much if any. Is the thread sealant, assuming incompatible or unknown, on the original heads, but not in contact with CPVC directly, ok?
