So with your scientific test... are you saying that FRAM is lying and the black is not silicone as they state on the box and the reply that I got from Fram????I’d say with confidence that the black adbv is not silicone but nitrile. It springs back slower and doesn’t feel as supple. If someone wants to try their own test go for it but I’d say it’s just nitrile. May just start using these for my cars. Cheaper than the extra guard, made in the USA and I’m guessing identical to the Mobil 1 m110, and the supertech mp7317

There are doctors that can help you......I want to draw the most negative conclusion possible that does not give Fram the benefit of the doubt whatsoever.
As the graph shows in post #146, the colder the temperature the easier it would be to see the difference between nitrile and silicone. Not rocket science.Just noticed I have some "nitrile" gloves , and they are blue. Maybe I should freeze them. Of course then someone will pipe up and say yur freezer wadn't cold enough, that's why you are wrong.
Thank you for checking this. @nthach is also checking one, though from your observations, with the red valve being more supple than the black one under the same conditions, it sounds like what we've suspected and the black valve is nitrile.I’d say with confidence that the black adbv is not silicone but nitrile.

My prior comments assumed that a typical freezer is at most 0F (-18C), so typical is likely -5 to -15F.What was the temperature in your freezer? Mine runs at around -10 to -15 F (-23 to -26 C). The freezer tests I've done with both a nitrile and silicone ADBV, I could definitely tell a difference between them.
Ok, nobody is arguing, just presenting information. I learned something today, thanks.I froze the Toyota and it wasn’t stiff at all. It doesn’t prove it‘s silicone. If it was stiff it may be nitrile, but it doesn't prove it. Arguing all done. Internet arguing what a time dump it is.
Most nitirile doesn't like temperatures over around 250 F (120 C). Any idea how hot the oil runs in the vehicle?There's definitely different grades of nitrile-the Purolator made QS filters are the ones that had rapid issues, the ones Baldwin/Clarcor use seem to be comparable to cheaper silicone ADBVs. I wish my brother's old Tercel was still around, it ate the QS ones like candy, while an FL-400S would last 8000+ miles. It's going to take running one of these black ADBV EG filters hard, in hot conditions, to determine whether they're good enough or not.
Maybe we’re going about this the wrong way-maybe baking nitrile & silicone ADBVs in an oven for 250-300F for an hour would be a better test? Seems like heat is the cheap ADBV’s real enemy.Most nitirile doesn't like temperatures over around 250 F (120 C). Any idea how hot the oil runs in the vehicle?
Like mentioned in another thread, the flame/match/lighter test to see how it burns would be simple and show if they are nitrile or silicone.Maybe we’re going about this the wrong way-maybe baking nitrile & silicone ADBVs in an oven for 250-300F for an hour would be a better test?

So my experiment ended up in flames, literally. It’s a nitrile ABDV. A sneaky cost-cutting move. I’ll buy OCOJs, but keep them in service for no more than 5K.Thank you for checking this. @nthach is also checking one, though from your observations, with the red valve being more supple than the black one under the same conditions, it sounds like what we've suspected and the black valve is nitrile.
