Says HNBR (nitrile), then says Silicon?interesting about #9. i will have to do a burn test on my Carquest Extended protection. looks a lot like nitrile to me.
Does no one check marketing stuff anymore?
The gasket on my Carquest Premium is red, so I would guess its silicon - but honestly I have never had a properly installed nitrile gasket leak so really isn't a big deal to me. ADBV in silicon is really a good idea however.
