Puro-Core?

[motorguy222]

In an earlier topic,Purolator is seeking a patent for a combo by-pass/ADBV.

Now it seems that they are wanting to get rid of the metal endcaps and possibly other components in the filter.

New Design

Can you provide a citing where it specifically says "they are wanting to get rid of metal endcaps?" All that I read in the application is the materials the endcaps "may" be made of. And what are the other components they would possibly eliminate besides the leaf spring retainer this replaces?

All that is posted here is the dome end of previously posted thread end combo valve design. Apparently this adds redundancy to the bypass component of the thread end combo valve bypass. In other words, the dome end of this design will combine(combo) a retention/support for the centertube/media(core), and an additional bypass(relief) valve in the dome. It also says that materials such as silicone can be used. The use of an additional bypass/relief valve and possible use of silicone, as opposed to nitrile, would be different than the current Champ ecore or selective Napa Pro Selects using a combo valve design previously posted here. Saw no mention of nylon cage (ecore) centertube in the application.

Still a long way though from a patent application, to standard production design use in P1 and or Classic. Clever trollish title though.

fwiw, I prefer reading the link directly from the pdf link below.

That's job security in action right there. I suppose it is an invention when you take others original creative ideas and modify them. It makes sense to reduce manufacturing wastes and reduce "no value added" components, as they say. It is not really for "no value added" though, it is because they have to sell filters for $3 and can't make any money on'em.

I was more interested in seeing in the drawings the seam between the can and the baseplate. I didn't realize the baseplate is held in just by the rolled can edge like that. No wonder they blow out at the seam.

Very good information to see.

First,I am not trolling.I think that it is safe to say that the vast majority here have better things to do than 'troll'.

I have been a member of this site since March of 04 and have 1400 posts.You have been a member of the site since 08 and have over 3500 posts,are you trolling?

Now,when you read the description of the new design,its states the following:


[0049]The invention is aimed in part to eliminate the non-value adding parts and processes used in manufacturing conventional filters, and to bring about a simplified assembly. In the present invention, an exemplary fluid filter is radically re-designed to replace various components like the bottom support-guide (spring), end cap, bonding plastisol/glue, relief valve spring, piston, relief valve housing/U-clamp, etc., with a two part combination relief valve element, which integrates the relief valve, the filter element supports and various seals.

[0050]The processes involving heating ovens for curing and bonding, welding and riveting processes used conventionally to manufacture the filter are also avoided according to embodiments of the invention. All these parts and processes are superseded by the two part combination relief valve element according to embodiments of the invention. The exemplary two part combination relief valve element may be molded from resilient silicon, nitrile rubber materials, compounded plastisol, polyurethane, resilient polymers or any other compounds and materials having the appropriate properties.


If you take out the processes that the design here does,there is quite a bit of evidence that there will be no metal endcaps.If you remove the very processes that are used for metal endcaps,that pretty much says that they will not be metal.It states that they want to do away with the present design,inluding the endcaps along with the sealers involved,that leaves little room for a metal endcap.

The description here sounds more like an E-Core design and process and may even mean doing away with an endcap altogether as some other manufacturers have done.

I can see why some dont post very often,they get bashed for doing so.

The "ECORE" as designed by Champ specifically implies a cage made of nylon used as the centertube. The two recent threads, and copy/paste here specifically refers to use of silicone or nitrile as combo valves, one for the dome end and one for the thread end to replace metal bypass and leaf spring. Nowhere that I read is there mention of a nylon cage as a centertube.

Napa ProSelect uses a similar designed thread end combo valve design, have yet to see it referred to as an ecore.

As for the endcaps, I asked for a citing where it says they are getting rid of metal endcaps. Haven't seen it yet. Seen some supposition, not much more. Anything is possible, since it was posted, just didn't read it specifically in the application.

So, your definiton of ecore would be different than mine. If and when I see nylon cage centertube with felt like endcaps, then I'll agree it's an ecore. Until then it's a similar design to the Napa Pro Select.

But you're right, if you didn't or don't know the difference, then it's not trolling. My apologies.

The problem with this "no value added" parts removal is the end user is the guinea pig. I would have to see a couple years of real world use and reports from early adopters, like on this site.Like low end Fram and the ecore parts removal designs.

 

[motorguy222]

If there are no metal endcaps,it is quite possible that the center tube will also change.It seems clear that Prolator is trying to cut costs and that the insides of the filter may change.

If the metal endcaps are done away with,you will most likely have three choices.One,keep the metal center tube like Fram has done.Two,make a filter that is similar to Champs E-Core design.Three,make the filter with no endcaps at all.This seems like a very plauseable scenario since this would fit well into the description of the filter.

The first option should get a lot of bashing since it is similar to Fram and Fram gets enough bashing for all of the other companies combined.If the Purolator goes this way,they had better be some bashing and lots of it.

The E-Core design isnt really that bad,if the seal between the endcap and element is good and holds tight,that isnt a problem.The center tube or lack thereof is where the problem lies for many,including myself.The gaps in the cage dont give the element the support needed and seems to have allowed the element to push through and cause problems for some.

The third option has been used by other filter makers and seems to work well.The element is sealed on both ends by glue/sealer and there are no endcaps.

If Puro goes this way,it is to keep their profits and still have a filter that costs in the $3-4 range,the range that most DIY's look for and buy.

Agreed. I think few current users here, myself included, would choose this new design over the current classic design. While I like the idea of the extra bypass and possible use of silicone instead of nitrile, still would keep looking for the classic design, no matter the maker, Purolator or not.

Just wondering if like Napa Pro Select, it will be used in a less expensive lower end filter(s), rather than a replacement for Classic or P1. That would be fine, as there would be options. Don't know that isn't what Puro has in mind here?

 

[ZeeOSix]

If Purolator goes with this new design, I will not buy those filters. I'd rather pay $5~6 for a metal tube/end cap and spring loaded bypass valve then $3 for this new uncertain design.

 

[river_rat]

I will buy them if they end up working well for a year or two on the market. But I an suspicious.

 

[Herz]

They are worth a shot like anything else, labman would have a blast if they made a ecore clone. Where is labman anyways?

 

[crazyoildude]

if purolater changes their filters i will be using napa all the time

 

[motorguy222]

I made a new thread that supports the Puro-Core filter idea.You can find this information there.The thread is calledurolator May Replace Metal With Plastic.

There are links to the description and pics of the new design that they are seeking a patent for.

It seems Puro is seeking to drastically change their filter design.

 

[river_rat]

Better support the media better than ecore, or I'm done with them forever.

 

[rslifkin]

^ Agreed. Good media support is the key, not whether it's being supported by plastic or metal.

 

[river_rat]

That's the thing. If mashed potatoes could hold it together, I'd buy it. But it won't likely be reliable with that much space.
Just my personal opinion.
