That's what I've been saying. The freezer test should be good enough to let us know.

"Imo', if the "freezer test" is being proposed as a definitive test for nitrile vs silicone, then a 'control' adbv for comparison should be added to the test. Ideally imo, that control would be a silicone adbv from the same application. In other words, an orange silicone adbv from same application Extra Guard or Tough Guard.

read post #104 in this thread. We need better definition on what a "freezer test" is, but it definitely can differentiate materials.
Stuck home with the 'rona, sorry
I already saw the graph. The graph assumes all compounds are made the same and nitrile is a word for exactly one kind. I hope it isn’t said oh that’s wiki to dismiss concrete facts. What I said was correct. The freezer test does not prove the adbv is silicone. It seems fair to say it can prove an adbv is not silicone. Probably also depends on the manufacturer. They may think withstanding heat is the main reason for silicone. A better manufacturer thinks of everything.

If I get out later today I can pick up the extra guards if I can find one in every color at my local Walmart…another thought, any reason why I couldn't run the EG past 10k I’m thinking the life of the olm on my families Hondas

Agreed.
Well I got this reply a few minutes ago.... Dear Robert...Thanks for bringing this to our attention...Due to supply chain issues...This line of filters now use a black silicone anti drainback valve...instead of the usual orange... The valve is still silicone but is now a different color...
Supply chain issues make sense..a corporation like this wouldn't take up the liability of labeling the box silicone and then using nitrile. Nothing to see here. The purple ones are used in the supertech 20k MP line and royal purple I suppose.
O I see many posting that they are liers....might see this get up to 10 pages in a day or two...
Yes, nitrile can represent various grades, but most have the shortcoming of having relatively poor elasticity at low temperatures. This is well known.
The chart cited is actually using a modern material for nitrile, older references show nitrile to be much worse, 100x more rigid at -20C.
And any further specialized material (for say aerospace) is going to cost 5-10x and there would be no motivation to use it in this application.
Bottom line, if it becomes stiff as a brick it is nitrile.
If not it is Silicone or some advanced material. Either way this would satisfy the concern, no?

They were shipping old Ultras in new boxes and vice versa, with the media description wrong.
See what I mean....
Any interest in a free XG7317? I have one I cannot use on anything, and I hate to throw it away but probably going to if I can’t find someone that can use it.
The modern facilities are generally automated injection mold processes that are very different from the archaic manual labor setup we used back in my time as a factory worker! Regardless, the modern processes are still limited by their supply.

I can use the XG7317, as that is what my Frontier uses. The one I have on now will be due to be changed next spring. How much to ship it to me at zip 68601?
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.
