Looking for a dimension

[Invader]

I could use the bore dimension of the bottom of a bauer p0/p21 filter tower, where the filter nipple goes in please.

TIA

Mate I thought you were in the outer limits, the thicker or thinner one

Both. My filter (without o rings) isn't going into the recess in the bottom.

Come on man how do I get those measurements without pulling my filter apart
Did you drop your eyeball down there what's in there an old oring, gremlin poo

I produced refillable catridges, they have 11.9mm and 13.9mm. So bore dimension is slightly larger, I expect 12 and 14mm.

Does you cartridge have a dammaged nipple?

No, they're new. But the LF filters won't go in, but the Bauers do. I'm trying to root cause the problem.

The O ring gap for the smaller O ring at the bottom of the nipple isn't as tall on the LF filter (3.1mm tall) as it is on the Bauer (3.62mm tall), and the O ring is slightly different. a dash 109 (7.59±0.13mm x 2.62±0.08mm) (according to Lawrence Factor on the phone) on the LF, and what looks to be a M7.5x2.5 on the Bauer. I wouldn't expect an imperial O ring to work on a metric recess, unless the nipple was machined to accept it, which it's not. The OD of the O ring groove is almost exact allowing for measuring tolerances and tool accuracy (7.91mm (LF) vs 7.86mm (Bauer)), leading me to the following conclusion for now.

I also measured 11.8/13.78mm on the LF, and 11.95/13.91mm on the Bauer OD sections above and below the O rings.

I *think* the O ring being imperial (and slightly larger), with the O ring groove being not as tall isn't allowing the O ring to squish into place and narrow down enough to get into the bore properly.

I have some M7.5x2.5 on order, to put onto the LF nipple to see if this corrects it. I've had to destroy LF filters to remove them with much force (which shouldn't be happening.)

I may have to do M7.5x2mm on a LF, but we'll see.

I am looking into the repackable idea now, but want to verify proper nipple machining and O ring tolerances prior to spending. LF Filters are priced better, and with better shipping options. Just paid $20 to ship 1 bauer filter to confirm my theories. Hell no.

You said, your filter does not match even without o-rings. So can not be (only) an o-ring problem.

Your LF filter nippel is even smaller than Bauer, so it should go into recess without problem.

What is LF filter? I don't know this kind of filter.

I will revisit the nipple problem once the bauer filter is depleted. I have tanks to fill at the moment.
