Fram PH3600 C&P. Pending tear?

[ZeeOSix]

Of course any wire or nylon mesh backed media isn't going to tear. Non-back media shouldn't tear nigher if the pleat spacing is done correctly. Wide pleat spacing is always seen on filters that have torn non-backed media.

everything you listed is what a premium guard is doing at the minute. i still use Fram Endurances weekly as i do premium guards.

this tier of filter is competing with jobber filters. the PH lineis built as cheaply as possible minus having a silicone ADBV. cheap filters are built to a lower standard than higher tier filters. look at purolator and fram. their lower tier filters are tearing. i am including the previous Mobil 1 filter and Ultra here. compare these to an endurance or a BOSS with reinforced dual ply media, they don’t tear. circling back to kschachn’s point, both of these filters are indeed flawed. Endurance currently doesn’t have a smooth leaf spring. this spans all of the Fram/champ filter lineup at the moment. The boss is built like an absolute tank yet has poor efficiency. this is why we are all hyper focused on Premium guard XL filters at the moment.

regardless, i will bow out now. thanks for the points and criticism.

And none of which actually relates to the use of eithe no end caps or fiber ones.

I will agree though that it is becoming a problem to find something that is both reliable and consequently efficient.

How about Donaldson white cans?

I don’t know about you but I have lots of options in my area. AAP has Car Quest Premium, O’Reilly has Micro Guard Select, Auto Zone has STP Extended Life (in my area) and NAPA has NAPA Gold. They are all pretty much Premium Guard clones. I have about 8 of those stores within 10 miles of my house.

I can also order PG filters on-line from both Amazon and Walmart. Amazon also carries Pentius XL filters than you can get at a good price and if you use Subscribe and Save you can save even more money.

When I saw the C&P of the Pentius, I almost wept a tear of joy. Now THAT is pleat spacing.

As Nancy used to say...
Just say no.....

You just aged yourself with that quote

^^^ Yeah, it was the wide pleat spacing causing the problem. Wide pleat spacing can cause media tears regardless of what the end caps are made out of.

Should be more pleats sharing the “work” inside the TG - will be a handy comparison when it comes out …

 

[Chris142]

this is why i refuse to run a paper end cap filter

The Purolators with metal ends tear too.

 

[4wd]

so you’re going to tell me that a PH and TG are in the same quality level of a premium guard or endurance?

It’s just a cheap/weak media - bonding to fiber end caps is strong like the way the PF63e was previously made - but yeah, I feel like Fram is doing more monkey business inside the can style - whilst the cartridge filters look better made …

 

[4wd]

These were better fiber end cap filters - but I think they wanted to standardize with metal end caps now …

 

[Lubener]

Has nothing to do with it. Tears happen with media bonded to metal end caps too.

 

[Sayjac]

"If" it isn't a "tear", one is imminent. And on this one the endcap deflection in that area not enough to save it as it does with some. As usual with tears seen, poor/wide pleat spacing in seam pleat area responsible.

Thanks for c&p.

I agree. I've seen more poor/wide pleat spacing on dissected Fram oil filters than on any other brand. I'd prefer the Walmart Super Tech filter to any current Fram except the pricey Endurance.

I suspect that so long as some of the mesh fibers are embedded into the epoxy (rather than solely the cellulose layer holding the pleat in place), which is highly likely, then yes, failure should be unlikely.

I only say this because of a quirky, unrelated failure at an aerospace plant I worked at. A rubber water hose failed under a sink, a hot water feeder line into the sink, causing minor flooding. But it was a stainless braided hose and the failure happened right at the juncture of the braided rubber into the brass connector, a small spot technically just beyond the braiding. I suppose you could have a similar quirky failure in a filter...in a small "unmeshed" portion of a meshed media right at the end cap. But yeah, unlikely.

Some vintage (and not so vintage) filter cartridges have perforated wraps around the media, essentially a sleeve with holes wrapped around (or slid over) the cartridge. Some of the older German filter applications, for example, like for BMWs and Mercedes. Might these wraps act as an oil pulse distributor and "shock absorber" that could reduce the tendency of wide pleats to stress and fail at their ends? The wraps are literally a physical barrier between an oil pulse and a pleat, kinda like a boulder breakwater in a harbor.

 

[ZeeOSix]

^^^ I don't think the outside sleeve was really meant to be a pulse/shock absorber. There really isn't much of a pressure/flow pulsation going on from the oil pump. I certainly could act more like a "flow distributor" to try and create a more even flow distribution.

I suspect that so long as some of the mesh fibers are embedded into the epoxy (rather than solely the cellulose layer holding the pleat in place), which is highly likely, then yes, failure should be unlikely.

Oil filter with the nylon mesh backing is bonded to the media, and if the manufacturing QA is right the ends of the backed media will be potted well into the end cap.

 

[Hohn]

I think it's possible to have quite excellent quality without metal end caps. Some of the Filtech/Roki filters have just thin plastic or fiberboard caps and they are excellent. But they also have higher pleat density as well, more like a PGI or Pentius.

There's an argument to make that an endcap made of a material similar to the media will assure the best potting integrity because similar material are easily and more effectively bonded. Metal being shiny and smooth is trickier to glue.

Other end cap designs can also be more space efficient and allow more media for a given can size. This is partly why I like the flat leaf spring design of the FIltech and some others.

I know leaf springs get a bad rap for being "cheap" (and for compromising end seal on the "leaky Fram" filters, but the leaf springs are more space efficient it seems.
