Re: Silicone and O2 sensors

["Joe Fulton" <jfulton@xxxxxxxxxxxxxx>]

According to what I read, the fumes which can harm an O2 sensor are produced
when some types of silicone rubber "dry".  These fumes are actually the
solvent being vaporized.  Although the article did not strictly pertain to
RTV (room temperature vulcanizing) silicone, it implied that the fumes were
generated when this material sets up in use.  I would think you would be OK
with any pre-formed silicone rubber product.

> I was Ebaying today and found a site that sells really cool looking
Silicone adapters, couplers and hose. The kind that all the air intakes use.
I am wanting to redo the end of the Wrangler piece I have for the 4.0L
American transplant to make it shorter. The question that came to my mind
is; Does the heat from an Automobile engine cause the Silicone to release
fumes that would damage an O2 sensor??? I realize that thousands of these
things are made and are out there. But, does anyone know if these type
fittings are safe? I mean let's be realistic, The big names may be using
good quality pieces that don't cause problems, but how do I know these
pieces are safe????? Anyone know or know how I can figure this out????
