FRAM EXTRA GUARD 10575 CUT OPEN

Technically speaking, if an oil filter is designed and made well it should be able to take some "rawhiding" (ie, abuse) if it's built to take the bypass PSI without damage. That is one goal of the design criteria of an oil filter. As seen in some C&Ps, some don't meet that design criteria. An ideal design on paper and how the manufacturing process meets the design drawing criteria are two different processes that need to align for a successful product to happen ... that goes for anything made by humans, lol.

I watched two YouTubes on oil filter manufacturing. One was by Fram (9 years ago) and the other by a Polish company (2 years ago). Both processes have a high level of automation combined with people doing select machine loading. Very impressive.

The media pleating, cutting, folding into a circle, fastening with the steel clip and insertion of the center tube is highly automated and very fast. Hot gluing to end caps is also automated. With the speed the process runs at, it is critical they have in-process gaging to prevent a lot of defects to be made in a very short period of time.

It's something us old codgers might say. You don't hear it much anymore, but it certainly is not BITOG specific and not "local". I suppose it could be regional to the south

Hi DuckRyder, I appreciated your reply . . . thank you.
