When did team extra guard switch over to silicone ADBV? #4977072

I just noticed at Wal-Mart the regular fram extra guard (3.77) now had a red silcone anti drain back valve. I think that's the cheapest filter I've seen one on. Anyone using them?

I believe it was during 2018. One of the few cheapies that has one.

It's a change we started hearing about maybe 6 months ago?

A silicone ADBV is actually a pretty cheap part to make, and really shouldn't be a "premium feature"

I'm still on the fence about the difference between silicone and nitrile, especially apps that mount filter down. Baldwin, Donaldson, and a couple other very well regarded filter makers use nitrile. Considering the difference is merely pennies, and those who use these filters depend on the quality of the item, you'd think that if it was actually necessary the manufacturers would make the change and charge a nickel more. Just my 2 cents.

I googled around a bit and found this interesting general nitrile/silicone comparison...
https://jehbco.com.au/silicone-vs-nitrile/
One thing that caught my eye is that silicone is listed as not being compatible with hydrocarbon fuels...would this be an issue with fuel dilution in engines?
Nitrile is shown as only being good up to 250F, which I imagine might be seen in cars used for racing...the highest I think I have seen was just under 220F.

I am not qualified to discuss the merits of this comparison, but maybe it can stimulate some discussion. I was surprised to see that nitrile can work down to lower temps than silicone, as I thought cold performance was a special strength of the latter.

That's the document I referenced as well to form my opinion.

Both materials are resistant to a range of chemicals. Nitrile has excellent resistance to hydrocarbon fuels and oils, making it ideal for automotive fuel applications. Formulations of nitrile containing phthalate plasticizers cannot be used with food or children’s toys. Silicone, on the other hand, is food grade and is often used in food and water processing equipment. For any application, it is important to check that the elastomer is resistant to the chemicals it will come into contact with.
I think they are trying to encourage the use of nitrile on fuel lines, rather than dissuade using it on ADBVs. That article does make the point that a silicone ADBV could be more effective at low temperatures.

I am surprised all missed the removal of the bypass filter screen on the Tough Guard filters.

Thanks for the good article.

For oil filter application, the preferred material choice for the ADBV is silicone. Silicone does not degrade over time like nitrile does. By observation, some of the nitrile ADBVs are very hard on dissection. The silicone ADBVs remain nice and pliable.

The -50C spec more than covers the oils useful starting temperature. CCS is specified at -35C for the 0W/xx oils and -30C for 5W/xx oils.

WRT fuel dilution, I don’t have this issue. It would be interesting to know if 5-10% would create an issue with a silicone ADBV. Maybe someone with fuel dilution issues can comment. smile

Nitrile swells in gasoline. An fkm rubber(Viton) would be a better option.

^^^^^

Well said. Silicone holds up to 230°C vs much lower for nitrile at 120°C. This may well be why nitrile hardens more than silicone after use in a oil filter.
Especially after longer runs above 10k miles and higher.

That has been gone for probably a decade.
Neat option though.

Yeah I'm using them. The PH8316 for the Zetec, and a PH7317 which is basically an A02
