Old Kralinator bypass filter

[TP4ME]

Picked up this old Kralinator bypass filter at the fleamarket for a couple of bucks, has a brand new wound cotton element. Inlet hole in central tube is about 1/32" dia. Would be interested if anyone knows when and what they were used on? Might stick it on a stationary engine with that old look. 1/8" steel throughout, made to last!

I've had some trouble figuring out how these things work. I assume that the flow originates from the outside of the filter and migrates to the interior. The center tube doesn't appear to have holes in it...so flow would be assumed to fill the interior column and spill over into the center tube. But the dimples in the bottom appears to offer the oil flow a short circuit to the center tube. That is, I can't see the fit of the metal end caps being tight enough to prevent oil from passing around both the end of the caps (the lower one anyway) ..or the center tube.

That is, unless the bypass filter is designed to internally bypass and is really a passive "perculator" type thing.

Anyone else see what I mean?

Flow is from the inside through the media and into the housing and out the side port.

According to my old Wix wall charts this might be a Kralinator model K-15 made for Ford/Mercury Flathead V8 engines. Note the angled mounting bracket, where it bolted on using the head bolts.
But I can't find a reference for that Fram filter number. what us the whole PN? the flash blocked the first part?

Most were used in bypass applications using "depth" type media.

Pete, thanks! The Baldwin cross-reference is where I got the "L55/K55" bit. The Baldwin number is C200-K. The Fram number is C-181-A. Was this the only filter on those V8s or an optional setup?

All the Flathead replicas have ONLY a bypass filter system. I don't think that they went to full flow until later on.

It has rubber seals at the top and bottom of the filter element, but judging by their tightness now, I doubt they would resist much pressure if the filter became clogged - but then maybe that is intentional. I had to really look to find the oil inlet hole in the central tube, it's about half way up on the mounting side and there seems to be only one. Turns out elements are still available from Baldwin and it seems to be a Kralinator L55 or K55

Does this kind of element filter any better than the usual types?

I'm assuming the central tube hole is the inlet, but considering the old Frantz filters restricted the output, not the input, maybe that was the intent here too. Oil pressure on the outside could help to seat the seals against the central tube perhaps?
